  • The destructive new logic that threatens globalisation | The Economist
    https://www.economist.com/leaders/2023/01/12/the-destructive-new-logic-that-threatens-globalisation

    America is leading a dangerous global slide towards subsidies, export controls and protectionism
    […]
    Yet rescuing the global order will require bolder American leadership that once again rejects the false promise of zero-sum thinking. There is still time for that to happen before the system collapses completely, damaging countless livelihoods and imperilling the causes of liberal democracy and market capitalism. The task is enormous and urgent; it could hardly be more important. The clock is ticking.

    décidément, The Economist ressent fortement une montée des périls, après le chaos possible à la Chambre des représentants états-unienne (cf. post précédent), la montée du protectionnisme et la perspective de guerres commerciales avec le retour d’une logique de jeux #à_somme_nulle.

  • Elon Musk’s $44bn education in free speech | The Economist
    https://www.economist.com/leaders/2022/12/19/elon-musks-44bn-education-in-free-speech

    He has had a crash course in the trade-offs in protecting free expression on Twitter

    Elon musk’s two months running Twitter has been an unhappy experiment. The social network’s 250m users have endured a wearying saga in which Mr Musk is the central character. Advertisers have fled. Twitter, which lost $221m in 2021, is now on track to lose $4bn a year, by one estimate. The damage has spread to Tesla, Mr Musk’s carmaker, part of the reason it has lost half a trillion dollars in market value since early September, costing Mr Musk the title of the world’s richest man.

    On December 19th it looked as if Mr Musk might throw in the towel, after he asked Twitter users whether he should step down as Twitter’s chief executive. It has been a costly adventure. But in one sense his turbulent stewardship of the social network has done the rest of the world a favour. In two short months Mr Musk has been through a public crash course in the principles of free speech, neatly demonstrating the trade-offs involved in protecting expression online.

    From the outside, Twitter seemed simple to someone whose day job was building self-driving cars and space rockets. Mr Musk, a self-described “free-speech absolutist”, had grown concerned (with some justification) that Twitter had been captured by censorious left-wing scolds. Shortly after agreeing to buy the platform he explained his approach to moderation: “By ‘free speech’, I simply mean that which matches the law.”

    In practice he has found that the right to speech conflicts with other rights. One is safety. Last month Mr Musk said that his commitment to free speech meant he would not ban a Twitter account that tweeted the whereabouts of his private jet, even though he considered this a security risk. But on December 14th he changed his mind after a “stalker” bothered his son. After suspending the jet account, Twitter introduced rules outlawing the reporting of others’ real-time locations.

    As well as limiting speech in the name of safety, Mr Musk has curtailed it to avoid the lesser sin of causing offence. In October the number of views of tweets that Twitter deems “hate speech” doubled, as users tested the limits of Mr Musk’s regime. Rather than allow this legal-but-nasty content, Twitter cracked down. In November hateful tweets recorded one-third fewer views than before the takeover. Earlier this month Twitter suspended the account of Ye, a rapper formerly known as Kanye West, after he posted a picture of a swastika within a Star of David—an image that, however grotesque, is nonetheless permitted by America’s laws.

    Mr Musk even limited speech when it was bad for profits. After pranksters sent tweets aping brands like Pepsi (“Coke is better”) and Nestlé (“We steal your water and sell it back to you lol”), Twitter outlawed such behaviour to stop advertisers fleeing. Then, to stem an exodus of users, on December 18th Twitter said it would ban people from linking to rival social networks or posting their usernames. When questions were raised as to whether regulators would consider such a move anticompetitive, Mr Musk apologised and free speech was restored.

    All this holds two lessons for whoever follows Mr Musk as Twitter’s boss, should he leave. One is to keep content moderation at arm’s length. The person deciding whether a post is acceptable is compromised if they are also responsible for boosting engagement among users and spending by advertisers. Mark Zuckerberg (whose reputation has risen in light of Mr Musk’s pratfalls) realised this and outsourced Facebook’s moderation headaches to an independent “oversight board” in 2020.

    The second lesson is that moderation has no clean solutions, even for “technokings” with strong views on free speech. Free expression is not a problem with a solution bounded by the laws of physics that can be hacked together if enough coders pull an all-nighter. It is a dilemma requiring messy trade-offs that leave no one happy. In such a business, humility and transparency count for a lot.

    These are novel concepts to some in Silicon Valley, who are impatient to tear up the established ways of doing things. But just as cryptocurrency enthusiasts have recently received a bracing lesson in the value of boring old financial prudence, Mr Musk and his fellow free-speech enthusiasts are learning why free expression has caused so many to scratch their heads for so long. Tech valuations have suffered a sharp correction in 2022. It has also been a chastening year for tech egos.

    • An interview with General Valery Zaluzhny, head of Ukraine’s armed forces | The Economist
      https://www.economist.com/zaluzhny-transcript

      The Soviet Army welcomed and enforced one concept: the commander. But being a commander and being a leader is not the same. With all due respect to Mr Surovikin [the commander of Russian forces in Ukraine], if you look at him, he is an ordinary Petrovite commander from Peter the Great’s time, shall we say, a derzhimorda [a brutal martinet in Gogol’s “The Government Inspector”].

      You look at him and understand that either you complete the task or you’re fucked. And we had long realised that this does not work. And we had particularly realised this in 2014, when 21-year-old lieutenants came to command men who were in their 50s and 60s. Of course we had our own derzhimordas who tried to keep order with their fists and biceps, but it does not work 100% in the Ukrainian army… It is always possible to be normal. To be normal means to remain human in any situation—that is the most important thing. To remain human, to become a leader. To be smarter, to be stronger, to be more talented and in that case try to manage people. That is a religion I practised.

  • The changing ideology of Silicon Valley | The Economist
    https://www.economist.com/podcasts/2022/12/14/the-changing-ideology-of-silicon-valley

    Podcast avec Margaret O’Mara et Adrian Daub.

    STARTUP FOUNDERS in Silicon Valley are often motivated by an almost religious idealism: young tech workers, looking to move fast and break things, want to use technology to make the world a better place. But 2022 has brought about a reckoning: the business models of once-star firms, such as Uber and Meta, are under threat; the allure of the dishevelled whizz-kid has been undermined by the downfall of Sam Bankman-Fried; and the expense of Palo Alto has pushed plucky startups out. The Bay Area has often been populated by liberals, but many of tech’s heroes, like Elon Musk and Marc Andreessen, have shifted to the right.

    On this week’s podcast, hosts Mike Bird, Soumaya Keynes and Alice Fulwood ask whether Silicon Valley has lost its religion. Margaret O’Mara, professor of history at the University of Washington, reveals the Valley’s past. And Adrian Daub, the author of “What Tech Calls Thinking”, tells us that the secret of the successful founder is to bamboozle regulators while they make a bit more money. Runtime: 41 min

  • Hydrogen hype is rising again—will this time be different? | The Economist | 14.11.22

    https://www.economist.com/the-world-ahead/2022/11/14/hydrogen-hype-is-rising-again-will-this-time-be-different

    Investors have been excited, and disappointed, before [...] But the biggest force pushing hydrogen forward in 2023 will be a tidal wave of government money in America.

    There is much enthusiasm about green hydrogen in Europe too. “Europe has been pregnant with a lot of projects but will finally give birth in 2023,” says Daryl Wilson of the Hydrogen Council, an industry body. He expects the regulatory uncertainty that has held back many of those projects to be cleared up. Mr Heid [Mc Kinsey] predicts that Europe will conduct the first global auction for hydrogen supply and demand, and that the European Commission will set up a European Hydrogen Bank in 2023.

    The Inflation Reduction Act, which is really a climate-change law, offers a staggering $3/kg in subsidy for green-hydrogen projects. Unlike Europe’s thicket of rules, America’s hydrogen policy is clear and extremely compelling, experts say. Many green-hydrogen projects, currently unable to compete against dirtier forms of hydrogen (which typically cost around $2/kg), will suddenly enjoy costs below $1/kg. In sun-kissed or wind-swept areas, some may even see negative costs.

    Mr Heid predicts that America will leapfrog Europe in attracting hydrogen projects, with total investments possibly reaching $100bn by 2030. The global hydrogen race is hotting up, and 2023 looks to be a make-or-break year. Watch this gas.

  • Europe’s Liveability Index : Back to Normal | The Economist | 19.09.22

    https://www.economist.com/graphic-detail/2022/09/19/the-most-and-least-liveable-cities-in-europe

    For many people in western Europe, the pandemic is a thing of the past. Mask-wearers are a small minority and lockdowns are a distant, if painful, memory. This return to normality is reflected in a survey of “liveable” cities compiled by the eiu, our corporate cousins. The index compares 172 cities around the world across five categories: culture and environment, education, health care, infrastructure, and stability. Many of the world’s most liveable cities in this year’s edition are in western Europe: Vienna took the top spot for the third time in five years. Two others, Copenhagen and Zurich, make it into the top five.

    The reopening of cities across western Europe has returned the region’s average scores to something close to their pre-pandemic norms. That also makes it the most liveable region globally.

    • [...] the most liveable region globally. In the overall list, all but one of the ten biggest improvements in the year were made in western Europe (the exception, Los Angeles, climbed 18 spots). The top three movers were in Germany: Dusseldorf, Frankfurt and Hamburg improved their liveability thanks mainly to big leaps in their culture scores after covid measures were eased.

      Not all corners of the continent have enjoyed the same improvements. By comparison, cities in eastern Europe are recovering from covid-era drops in liveability at a slower pace; the average score in the east is now 20 points lower than the west. Already-strained health-care systems have been hamstrung by slow vaccine rollouts; many cities remain rife with corruption. Istanbul, the only city in Turkey included in the ranking, had the lowest score in Europe. Increasingly authoritarian leadership under Recep Tayyip Erdogan, the country’s president, as well as eye-watering inflation have dampened the quality of life. Baku, the capital of Azerbaijan—one of the most corrupt countries in Europe according to Transparency International, an anti-corruption group—is the second-least liveable city in Europe, reckons the eiu.

      Moscow and St Petersburg slipped as Vladimir Putin’s regime tilted further towards oppression. The unit’s analysts were unable to finish their survey for Kyiv after Mr Putin’s invasion earlier this year. Ukraine’s capital has come either last or second-to-last in the European rankings since 2014.

      The fighting will continue to make its mark on much of Europe. Inflation has hit Europe particularly hard, given the dependency of many countries on Russian gas. Higher prices will make the joys of city life less attainable. And a looming recession will take the shine off post-lockdown living.

  • The Economist – Frozen Out – How the world is leaving Europe behind
    https://view.e.economist.com/?qs=706216167d7a949d1a8bf6762ff02aee5f6fad9c0f66eae10826eea83914a3

    Vladimir Putin, Russia’s president, is using energy as a weapon. Our data journalists set themselves a difficult question: how many people is this weapon likely to kill outside Ukraine? The answer they came up with was alarming. Although heatwaves get more press, cold temperatures are usually deadlier than hot ones. To estimate the relationship between energy costs and deaths, we built a statistical model that predicts how many people die per winter week in each of 226 European regions. This model found that a 10% rise in electricity prices is associated with a 0.6% increase in deaths, concentrated among the elderly and infirm. If the historical relationships between mortality, weather and energy costs continue to apply—which they may not, given how high current prices are—the death toll from the energy weapon could exceed the number of soldiers who have died so far in direct combat from bullets, shells, missiles and drones. It is one more reason why Ukraine’s fight against Russia is Europe’s, too. 
     
    Our data team’s work sets the scene for our cover this week. Europe faces a crisis of energy and geopolitics that will weaken it—and could threaten its global position. If you ask Europe’s friends around the world what they think of the old continent’s prospects they often respond with two emotions. One is admiration. In the struggle to help Ukraine and resist Russian aggression, Europe has displayed unity, grit and a principled willingness to bear enormous costs. But the second is alarm. A brutal economic squeeze will pose a test of Europe’s resilience in 2023 and beyond. There is a growing fear that the recasting of the global energy system, American economic populism and geopolitical rifts threaten the long-run competitiveness of all European countries, Britain included. The worry is not just about the continent’s prosperity; the health of the transatlantic alliance is at risk, too.

    Brazil has pledged to end illegal deforestation by 2028. However, Jair #Bolsonaro, the president, has relaxed enforcement of environmental safeguards. Satellite images suggest that twice as much forest has been lost in 2022 as the average for January to April in 2010-21. The future path of global warming depends in part on whether Mr Bolsonaro is re-elected this year.

  • Monkeypox : même pas peur | The Economist | 20.05.22

    https://www.economist.com/the-economist-explains/2022/05/20/monkeypox-is-popping-up-in-more-countries-how-worrying-is-this

    The virus is not very good at spreading, and existing vaccines can protect those at risk

    A GROWING NUMBER of countries are reporting cases of monkeypox, a rare viral illness typically found in parts of Africa. On May 7th Britain reported a case in a traveller from Nigeria. By May 20th America, Australia, Canada and at least eight European countries had reported dozens of confirmed or suspected cases. Britain reported 11 new cases on May 20th, more than the total in the previous two weeks. Many have no links to African travel, which means they were transmitted locally. In the past sporadic cases were almost always imported. All of this is alarming. But the world is far from helpless.

    Monkeypox is caused by a virus similar to smallpox, which was declared eradicated in 1980. Infections are usually mild, with flu-like symptoms. A rash that spreads all over the body can develop, turning into blisters and scabs. Infected people usually recover in a few weeks. As with other poxviruses, the disease is more severe in young children and people with weaker immune systems. How dangerous it is depends on which of the two strains of the virus is involved. One, mostly found in past outbreaks in the Congo basin, is fatal about 10% of the time. The other, west African strain is less severe, with mortality estimated to be around 1%. These estimates are from outbreaks in remote places in Africa with poor health care. In rich countries monkeypox would probably be a lot less deadly.

    A vaccine for monkeypox developed by Bavarian Nordic, a Danish biotechnology firm, was approved by American regulators in 2019. The vaccine is also approved for smallpox and data from Africa suggest that past smallpox vaccination is at least 85% effective in preventing monkeypox. America’s Centres for Disease Control and Prevention says the jab is most useful if given before or within four days of exposure to the virus. Even if it is given up to 14 days after exposure it may still help, by reducing symptoms. Evidence from animal studies suggests that some antiviral medicines used for other poxviruses may be useful too.

    Also encouraging is that the monkeypox virus is not particularly good at spreading between people, and nowhere near as contagious as (for example) measles. It was first discovered in Denmark, in a laboratory monkey (hence the name), but is thought to be mostly harboured by small rodents in Africa. In that continent many cases are acquired from wild animals, when people hunt them, handle the raw meat or eat it. For the virus to spread from one person to another requires close contact. It spreads through droplets from coughs and sneezes that enter the nose, throat or eyes. It can also be picked up through contact with the skin, clothes or bedding of an infected person who is shedding the virus from pustules or scabs. Symptoms usually appear five to 21 days after infection.

    The tricky part is diagnosis. A monkeypox rash looks a lot like chickenpox. Confirming it requires sending samples to a specialist laboratory equipped to handle highly dangerous pathogens. At the moment, Britain has only one rare-pathogens laboratory designated to run tests for monkeypox.

    That said, containing outbreaks of monkeypox should be relatively easy. Isolating confirmed or suspected cases and tracing their potentially infected contacts can stop chains of transmission. The smallpox jab will probably be used for “ring” vaccination of the close contacts of infected people and health workers at high risk. Britain and Spain are looking to stock up on the vaccine already. Ring vaccination of close contacts was successful in curbing some of the recent Ebola outbreaks in Africa.

    In the next few days and weeks more cases of monkeypox are sure to be found. But it is unlikely that the outbreaks will spread out of control. Covid-19 caught the world unprepared, with no drugs or vaccines at the ready. Monkeypox, however, is in an entirely different—and lesser—league.■

En dehors du fait que ça a les mêmes défauts que la plupart des docs Netflix (tout en prétendant le contraire, ça passe beaucoup de temps à te démontrer que lanceur d’alerte, c’est pas une bonne idée, en vrai), c’est intéressant du point de vue de la gestion du merdier  : on cache, on minimise, on rassure, on ment et quand la bombe à crottes explose, on perd la mémoire et on intimide les témoins.
      L’idée de base  : ne pas perdre de pognon, garder le pouvoir, quoi qu’il en coute, avoir ea + profond mépris pour la vie des #dispensables.

      Enfin...
      Oui.

Fallait pas vivre au Pakistan ou en Inde ce printemps. Fallait pas choper la variole en mai 2022. En Juin, ça ira mieux, on aura assurément établi le contact-tracing qu’on n’a pas voulu mettre en place pour le covid, et ça aura permis de découvrir toutes les personnes qui ont chopé le virus dans les dernières semaines. Faut être optimiste après tout. Nous sommes les occidentaux, et nous sommes les maîtres du monde.

      aussi, je me demandais si le tracking/backtracking covid était toujours actif, et s’il servait pour la pox.

    • Sur la transmission aéroportée, j’ai lu que du fait des petits effectifs observés jusqu’alors, ça n’avait pas pu être formellement prouvé, mais que c’était possible. Et quand y-a pas de preuves académiques et qu’on ne veut pas porter de masque, on dit qu’y-a pas de transmission par ce biais. Mais des sources non-polémiques disent que ça se transmet aussi par aérosols. On va le savoir tôt ou tard. Là, je trouve que ça se propage trop bien pour qu’on puisse exclure les aérosols. Mais peut-être que c’est vrai qu’on ne se lave plus les mains et qu’on recommence à se postillonner dessus les uns les autres.

    [...]

    The pandemic has engendered a huge expansion of state spending at a time when some of his labour-market reforms might have caused more tensions. He has also used the pandemic as an excuse to shelve pension reforms that might have hurt him.

    https://www.economist.com/leaders/2022/02/05/the-economists-election-modelling-should-cheer-emmanuel-macron

    • This election is worth watching closely. Mr Macron is bidding to be the leader of the European Union, which has a vacancy to fill. Olaf Scholz, Germany’s new chancellor, seems reluctant to take up Angela Merkel’s European mantle. Italy has dodged a bullet by avoiding an early vote, but still faces uncertainty. Britain is gone. France matters more than for a long time. It matters greatly who is in charge.

    • Pour dégrossir un peu le terrain :

      Fil de discussion : Comment rendre l’air des salles de classe plus sûr ?
      Tout ce que vous devez savoir sur les filtres HEPA, les moniteurs de CO2 et la ventilation. Contenu : idées de base ; comment faire avec des liens vers des ressources ; avertissements ; liens vers des études / preuves (que j’ajouterai car cela prend plus de temps) 1/.
      Les maladies respiratoires transmises par l’air (TB, Covid, etc.) sont toutes transmises de la même manière : l’agent pathogène se trouve dans de minuscules particules que nous expirons / dégageons en parlant. Elles sont suffisamment petites pour rester dans l’air comme de la fumée ; vous en recevez davantage si vous êtes plus près, mais finalement toute la pièce est enfumée 2/.
      Les gens les respirent et sont infectés. D’autres particules sont émises en parlant, en criant ou en chantant. Comme le virus se trouve dans ces mêmes particules, la variante du covid ne compte pas. nature.com/articles/s4159... 3/ Image
      Donc, si nous pouvons empêcher les gens de respirer les particules respiratoires d’une personne infectée, nous pouvons empêcher la propagation des maladies par voie aérienne. Il existe 4 moyens d’y parvenir : les masques, l’air frais (ventilation), le filtrage (HEPA) et la stérilisation de l’air (UV) 4/.
      Les masques sont bons. Bleu ("chirurgical") > tissu > rien. Ils empêchent principalement le porteur d’infecter involontairement d’autres personnes, donc il est bon que tout le monde en porte. (Empêche les particules d’entrer dans l’air par la bouche ou le nez). Les FFP2 / FFP3 bien ajustés sont encore mieux, ils protègent également l’utilisateur et peuvent être portés à nouveau.

      5/
      Cependant, les masques, bien qu’importants, ne sont pas suffisants pour de longues périodes de temps dans une même pièce (comme dans les écoles) et ne peuvent pas être portés pour manger et boire. De plus, il n’y a pas de masques dans les écoles primaires (élémentaires) du Royaume-Uni et ils ne constituent pas une (bonne) solution à long terme. Donc... 6/
      Deuxième option, expulser l’ancien air rempli de particules expirées avec de l’air frais ("ventilation") - mécaniquement par les conduits du bâtiment, ou naturellement en ouvrant une fenêtre. 7/
      La ventilation des fenêtres dépend du temps et peut être difficile à évaluer. Pour savoir si l’on a besoin de plus d’air frais, nous utilisons le CO2 pour estimer la quantité de particules respiratoires accumulées dans l’air (difficile à mesurer) - nous expirons les deux, et ils sont tous deux éliminés par la ventilation.
      8/
      L’air frais extérieur contient 400 ppm de CO2 (réchauffement de la planète !). Au-dessus de 800 ppm, >1% de l’air de la pièce a été expiré, il faut donc faire entrer de l’air frais en ouvrant les fenêtres. Un coup d’air rapide pour se rafraîchir s’il fait trop froid pour laisser les fenêtres ouvertes. D’autres bons conseils :

      Si vous avez une ventilation mécanique dans le bâtiment (beaucoup d’universités et d’écoles récentes en ont une), vérifiez que la personne qui gère votre bâtiment l’a réglée pour maximiser l’air frais (pas « recyclé »). Vous pouvez également vérifier que tout est en ordre avec un moniteur de CO2. 10/
      Si vous ne pouvez pas obtenir suffisamment d’air frais (vous ne pouvez pas ouvrir suffisamment les fenêtres / il fait trop froid) et que le CO2 est généralement supérieur à 1200 ppm à la fin du cours, vous pouvez également filtrer les aérosols infectieux présents dans l’air. Faites-le avec un HEPA ("high efficiency particulate air [filter]"). 11/

Il en faut 2 ou 3 par classe, répartis un peu partout (voir plus loin). [NB : ils n’éliminent pas le CO2, donc les moniteurs de CO2 ne montrent pas l’avantage du HEPA.] 12/ Image
      HEPA est une technologie bien établie, qui élimine toutes les particules de 0,1 à 10 microns, ce qui inclut les particules expirées porteuses de maladies transmises par l’air (ainsi que le pollen, la fumée, la pollution particulaire, etc.) "Le filtre HEPA H13 élimine 99,95 % des particules de 14 à 10 microns.

      Le choix d’un filtre HEPA (air) peut être déroutant, mais ce n’est pas nécessaire.

      Remarque : les modèles officiellement recommandés par le gouvernement britannique sont Dyson et Camfil, mais ils coûtent ££ pour l’air pur qu’ils fournissent. Les seules choses qui comptent sont le taux d’air pur (CADR), le coût et le fait qu’ils ne soient pas trop bruyants (la ressource ci-dessus inclut cela). Il est donc préférable d’avoir plusieurs unités moins chères dans la pièce. 15/

      Avec des taux de covidités élevés, il faut de l’air pur et des masques. En cas de face à face sans masque, la ventilation / HEPA / UV n’arrêtera pas l’infection : si vous êtes en face d’un fumeur, une fenêtre ouverte ne sera pas d’une grande aide s’il vous souffle de la fumée au visage. Les masques (en particulier les FFP2) assurent cette protection 17/.
      17/
      L’air frais, propre ou stérilisé est extrêmement efficace pour réduire la transmission et fonctionne sur toutes les variantes, ainsi que sur d’autres maladies infectieuses transmises par l’air. C’est un bon investissement à long terme, et c’est aussi très faisable. Finançons-le et faisons-le. /FIN
      Mise en garde : l’air pur est une couche supplémentaire. Face à face sans masque = risque encore élevé (surtout en intérieur). La distanciation est également utile (comme dans l’analogie avec le fumeur). Et sans la distance ou les masques, l’air pur peut encore faire la différence, par exemple en infectant seulement 1 ou 2 camarades de classe, et non 10. Mais ce n’est pas une solution miracle.

      Vous pouvez avoir des fenêtres ouvertes ET un HEPA. En fait, vous devriez faire les deux, si vos fenêtres ne fournissent pas assez d’air frais. C’est ce que dit @mjb302, qui participe à l’étude @AAirDStudy sur les HEPA à l’hôpital Addenbrookes de Cambridge.

      Vous pouvez trouver des unités HEPA sur Amazon (ou d’autres magasins). Recherchez « purificateur d’air HEPA » et cherchez « True HEPA » ou « H13 HEPA ». Ne prenez pas ceux avec ozone / ioniseur. Ne tenez pas compte de la surface de la pièce indiquée, recherchez le taux de diffusion d’air pur (CADR) et le niveau de bruit (dBA). Utilisez ensuite

  • As Americans cut the cord, Europeans sign up for more pay-TV | The Economist (11/09/2021)
    https://www.economist.com/business/2021/09/11/as-americans-cut-the-cord-europeans-sign-up-for-more-pay-tv

    Why has American media’s mega-trend missed Europe? One reason is price. America’s cable industry may look competitive: the largest player, Comcast, has only a quarter of the market. But it is highly regionalised, so most homes have few options, says Richard Broughton of Ampere. The result is an average monthly cable bill of nearly $100. British homes pay less than half as much. Tax loopholes have made pay-tv an even better deal in parts of Europe. Take-up in France rocketed from 30% to 90% between 2004 and 2014, after the government imposed a lower rate of vat on television services than on telecoms, unintentionally giving phone firms an incentive to throw in a cheap tv package and pay the lower rate of tax. The loophole has been closed, but subscriptions remain high.

    A second factor is content. American cable tv is running out of shows as studios move their best ones to their own streaming platforms. In Europe, where some streamers have yet to launch, pay-tv firms retain the rights to many of the most popular titles. Britons seeking the third season of WarnerMedia’s “Succession”, for instance, must go to Sky, a Comcast-owned satellite firm, since Warner’s hbo Max has yet to stream outside the Americas.

    The last reason Europe still favours cable is that American streamers have forged partnerships with European pay-tv firms rather than competing with them. In the race for subscribers, the quickest way for streamers to bulk up in Europe has been to join forces with satellite and cable incumbents. They are the ones with access to consumers and the ability to handle local marketing and ad sales. In Spain, Vodafone offers bundled subscriptions to Netflix, Disney+ and others. Next year Viacomcbs’s Paramount+ will launch in six European countries on Sky’s platform.

    Will cord-cutting eventually cross the Atlantic? As long as Hollywood studios continue to license their programming to local players, consumers will have every reason to stick with pay-tv. For the studios themselves those deals are lucrative, points out Mr Broughton: “Doing a Disney and cancelling all those contracts, then replacing them with your direct-to-consumer service, leaves you with a bit of a gap in your financials.”

    In the long run, though, studios would rather bring viewers onto their own platforms, as in America. In that scenario, pay-tv firms may be left with little to offer but sport, alongside streaming bundles of the sort offered by France’s Orange or Britain’s Virgin Media. Warner plans a gradual European roll-out of hbo Max over the next few years. By the time the fourth season of “Succession” is out, audiences may be watching it online.

  • Movie Business / Streaming has changed the economics of talent : how Hollywood’s biggest stars are losing their clout | The Economist (13/11/2021) https://www.economist.com/business/how-hollywoods-biggest-stars-lost-their-clout/21806186

    (…) In total, streaming firms’ content spending could reach $50bn this year, according to Bloomberg.

    Yet despite the largesse it is a turbulent time in Tinseltown, as everyone from a-list stars to the crews who style their hair goes to war with the film studios. Some of the disputes have arisen from the pandemic, which has upended production and release schedules. But the tension has a deeper cause. As streaming disrupts the tv and movie business, the way talent is compensated is changing. Most workers are better off, but megastars’ power is fading.

  • Why Europe is a great place for digital nomads | The Economist

    Why Europe is a great place for digital nomads
    A varied continent with good WiFi and few internal borders
    AFTER MONTHS in lockdown in grey Berlin, Chris Bloom, a personal coach and blogger, planned his escape. Risking the ire of jealous Instagram followers, he took a covid-19 test, flew to Lisbon and settled into the Outsite co-working and co-living space, a pleasant blue-and-white tiled property with the essentials—stable internet and a coffee shop. Mr Bloom is part of a growing brigade of digital nomads in Europe, who work remotely while satisfying their wanderlust. This kind of itinerant lifestyle is as old as laptops and free internet. But covid-19 has given it a boost. A game of lockdown arbitrage began earlier this year as border controls eased and people fled congested cities like Berlin and London. Some headed for other cities, such as Lisbon and Madrid, which offered sunshine and looser lockdown rules. Others chose remote spots on the Mediterranean and in the Alps. Now covid-19 restrictions are easing but the trend continues as many Europeans reject a traditional office routine after a year and a half of remote work.
