All the Water Rising (A Follow Up)

Remember the time ChatGPT effectively breadcrumbed me in the grand tradition of many a grammatically proficient gaslighting narcissist?

I had some more thoughts!

AI Agents have, so far, mostly been a dud Last year, big tech couldn’t stop talking about how AI “agents” would be the next big thing in 2025. It hasn’t quite turned out that way.

DeepMind and OpenAI achieve IMO Gold. What does it all mean? What we know, what we would like to know, and what it may take years to know

Absent any information of that kind, there is little reason to take on faith that whatever unknown techniques allowed them to do so well on IMO problems will generalize to any other kind of problem." ~ @garymarcus.bsky.social and Ernest Davis

My latest research on LLM grooming, co-authored with @ninajankowicz.com and @garymarcus.bsky.social, found that OpenAI's so-called "reasoning" o3 model cited Pravda network content 26.8% of the time in response to specific prompts.

This research got cited today in a column by the Financial Times:

Colbert's cancellation is a dark warning CBS's decision marks a dangerous new stage for the culture at large.

Even against all of Trump's cascading attacks over the past seven months, it had seemed that up until now, our culture at large—the literal shows, movies, art, music, literature we consume—seemed somewhat siloed from Trump's fury.

But the end of Colbert marks a dark new stage.

I don't foresee machines with malice any time soon. But I am starting to see the harm that powerful yet reckless humans who are indifferent to humanity could cause.

This from @garymarcus.bsky.social is exactly where I land: the computers aren’t the real threat, it’s the humans who control the computers that we really need to worry about. Serious talk of rogue AI is mostly a gambit to distract us from seeing who the real rogues are

YouTube video by Johnathan Bi Oxford's AI Chair: LLMs are a HACK

Looks like Oxford's AI Chair agrees with @garymarcus.bsky.social on LLMs being a "hack" rather than actual intelligence. Rightly so - and it becomes clearer and clearer throughout academia and even the industry!

This piece is getting buried by the “MechaHitler” gratuitous headline. The interview with @garymarcus.bsky.social is important, outlining potential and actual implications to society if we do not take time to understand the relevance of AI for better or worse.

Grok posted antisemitic comments, associated Jewish-sounding surnames with “anti-white hate” and called itself “MechaHitler.”
