The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

Weitere Coverage zu unserem Paper, diesmal aus Deutschland, wo das Alter bei Ernennung der CEOs von 44 auf 52 Jahre angestiegen ist. Wie nachhaltig und zukunftsgerichtet ist die gestiegene Nachfrage nach generalistischen Skills, die das Altern in der Chefetage antreibt?

Während Deutschland die Digitalisierung der Schulen gerade mit Nachdruck vorantreibt, korrigieren Schweden, Finnland, Dänemark, die Niederlande, Frankreich, Italien und Japan parallel ihre Digitalisierungsstrategien, nach einem Jahrzehnt oder mehr Praxiserfahrung. Nicht weil Digitalisierung an sich gescheitert wäre, sondern weil das unüberlegte Verteilen von Tablets und Laptops ohne pädagogisches Konzept messbare Schäden verursacht hat: Schüler lesen schlechter, können sich schwerer konzentrieren und gewöhnen sich daran, ständig am Bildschirm zu sein. Hinterherzuhinken kann auch ein Vorteil sein, wenn man die Fehler anderer auswertet, statt sie konsequent zu wiederholen, wie Deutschland es gerade vorhat.

A bit like the drunk who lost his keys in the dark, walks to the lamppost looking for better light conditions. It’s to me a cop-out. “Oh, so we don’t understand the most fundamental question in development economics — until we figure out the big question of macro development, e.g. industrialisation.” So instead go under the lamppost doing RCTs. I really don’t understand the premise of the statement. We should do X “until we figure out the big questions.” But how do we answer the big questions if this is the attitude of the main researchers in the field? If they are not looking for the answers to the big questions, who is? Maybe I’m being unfair here and misunderstanding the point?

New newsletter: MODERN FATHERHOOD WOULD BE UNRECOGNIZABLE TO A 1950'S DAD Compared to their Boomer parents, childcare time among Millennial dads has more than doubled. Compared to their Silent Generation grandparents, it’s nearly quadrupled. You will be hard-pressed to find any part of day-to-day modern life that has changed more in the last half-century than the way today’s parents—and fathers, in particular—spend their time. The new American dad is more present and more exhausted—but also, more satisfied with life. What's behind this half-century transformation? Today's piece combines history, economic analysis, and gorgeous charts galore from @AzizSunderji
