I read the piece again and became even more disappointed.

2026: "Docter said Pixar found some parents didn’t want entertainment to force them to have a conversation they weren’t ready for with their children. “We’re making a movie, not hundreds of millions of dollars of therapy,” he said."

Hostias, hay un género que ha muerto, el thriller político. Antes había que estudiar un fajo de papeles escondidos bajo la cama de un coronel asesinado para descubrir que una guerra era ilegítima. Ahora te lo cuentan los culpables en una rueda de prensa después de tirarse un cuesco.

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers I’ve read in awhile.

Lo imposible Gracias al pasado sabemos que un Frente Popular no es la suma de detalles por parte de las formaciones, sino el abandono de detalles por parte de las formaciones

Un FP es una palanca a accionar en momentos de avería. La función principal de un FP es evitar un gobierno no democrático. Un FP consiste también en diferenciar, al vuelo, la política institucional de la política social.

Consultar el estado de los parques en la web oficial es un horror (un mapa con una leyenda de colores) Así que he hecho un bot que, cuando cambia el estado de algún parque, lo comparte con todo Bluesky.

The reason why RAM has become four times more expensive is that a huge amount of RAM that has not yet been produced was purchased with non-existent money to be installed in GPUs that also have not yet been produced, in order to place them in data centers that have not yet been built, powered by infrastructure that may never appear, to satisfy demand that does not actually exist and to obtain profit that is mathematically impossible
