On me répète que ceux qui n'utilisent pas l'IA seront désavantagés par rapport à ceux qui l'utilisent.

Combien de temps avant que le problème ne s'inverse complètement ? Que ceux qui savent encore créer et faire des recherches soient avantagés pour n'avoir pas désappris leur métier ?
I keep hearing that folk who don't use AI will be at a competitive disadvantage compared to those who do

I wonder how long before that flips completely, and there's a big market for people who still have basic creative and research skills

How much worse can it get?
Way mo’!
Around half of San Francisco is without power right now and something like 1/3rd of intersections I drove through had waymos stopped in the middle of them making a dangerous situation even worse.

Do not let Waymo into your city.

It's amazing that in those lists, they never identify "Brave New World" (from Huxley not the MGU) as the main opponent of what the US created....

It's like, they never read a single book...

Je suis toujours surpris de voir des défenseurs de l'idée de faire une thèse de x ans non financée, soit:
- il y a un job alimentaire à cote et ca induit que la recherche est un hobbie
- soit c'est réservé à une classe sociale qui peut se permettre de ne pas avoir de salaire pendant 9ans
