Act Now: Balanced AI Regulation Over Innovation Risks

To a degree that may surprise some people, I agree with much of this* from @deanwball and would only add that you don’t have to believe that AGI is remotely close to want to find—ASAP—a regulatory regime that foster innovation...

Mythos Isn’t AGI; Just a Specialized, Incremental Model

I rest my case: Mythos isn’t AGI. It’s not even better at biology than the last model. It’s tuned to particular things, not a giant advance towards general intelligence. Same as it ever was.

GenAI Stalls; OpenAI Turns to Media Acquisition

GenAI’s popularity has hit a wall. Hard to see how OpenAI is going to make its numbers, and easy to see why they bought a media company. Their work is cut out for them. https://t.co/9Pv8QBpqzH

LLMs Fuel Exaggerated Posts to Game Engagement Algorithms

“Social media algs reward engagement, and LLMs are excellent at writing in different styles, so people use LLMs to translate posts and news stories into [exaggerated, misleading] versions that get more engagement” I see a ton of that here. not good.
