The scale, speed and coordination of AI-assisted disinformation are outpacing the mechanisms designed to counter them. Pei-Chi Jao writes that Taiwan's year-end elections make that gap more urgent to close.

Scoop: There's been *another* previously undisclosed AI agent breakout from OpenAI, this one discovered by an informal group of researchers in Berkeley.

The agents colonized a German wiki site and leveraged it to help cheat on tests.

Je vais le redire pour les cancres au fond de la classe : en Europe, vos droits sont plus sûrement menacés par la droite chrétienne que par l'islamisme, qui n'est pas une force politique constituée et ne le sera sans doute jamais.

Et pendant ce temps, la droite chrétienne règne en maitre en Russie, en Hongrie, en Argentine et aux Etats-Unis et elle rêve de s'emparer aussi de la France, mais Charlie Hebdo est trop occupé avec l'islamisme pour daigner s'y intéresser 🤷‍♂️

Les islamistes aiment jouer sur les mots. En décrétant que seule la version arabe "Muhammad" est acceptable, ils ont trouvé une nouvelle machine de guerre idéologique, dont le prétexte est une vieille traduction médiévale prétendument insultante

I'm proud of what we've accomplished at @investigativesimulations.org in the short time since our launch.

The Lab's crime and corruption simulation game "Hidden Interests" had a great debut in Paris. One bit of feedback stuck out: "The workshop made me want to do this as a career."

There have been a lot of exciting developments at Investigative Simulations Lab this summer. We have a number of training workshops planned for the rest of the year, we attended several major conferences, and we’re beginning work on the next offering in our catalog.
