AI materials discovery now needs to move into the real world

The microwave-size instrument at Lila Sciences in Cambridge, Massachusetts, doesn’t look all that different from others that I’ve seen in state-of-the-art materials labs. Inside its vacuum chamber, the machine zaps a palette of different elements to create vaporized particles, which then fly...

Le chercheur Nate Soares, « doomer » de l’IA à Berkeley, prévoit la fin de l’humanité : « C’est de la folie de les laisser essayer »

Passé par Microsoft et Google, aujourd’hui à la tête d’un laboratoire consacré à la recherche sur l’intelligence des machines, le chercheur prévient : l’homme ne contrôle pas complètement le développement de la superintelligence sur le point d’émerger. Au risque que celle-ci cherche à le détruire.

This medical startup uses LLMs to run appointments and make diagnoses

Imagine this: You’ve been feeling unwell, so you call up your doctor’s office to make an appointment. To your surprise, they schedule you in for the next day. At the appointment, you aren’t rushed through describing your health concerns; instead, you have a full half hour to share your symptoms and...
