Analogy and metaphor galore!

I was interviewed by the @nightsciencepod.bsky.social podcast about metaphor and analogy in science:

Pairs well with @sflusberg.bsky.social's interview on metaphor on the @manymindspod.bsky.social podcast

Phil, thanks for your clarifications on this. Yes, there were many scientists in Epstein's cabal, but it would be tragic if that fact leads to even more anti-science sentiment in the public (as well as conspiracy thinking about even simple algorithms).

P.S. For people who listened to the show: It turns out that Claude's "funnier" (and NSFW) joke was taken almost verbatim (and without citation) from a three-year-old Reddit post. So my guess that it was in the training data was correct!

On Brian Cantwell Smith and the Promise of AI Today I had the bittersweet pleasure of participating in a symposium honoring the late philosopher Brian Cantwell Smith, a good friend whom Iโ€™d known for over 30 years.

I wrote about the late philosopher Brian Cantwell Smith, and his profound thinking about AI and the nature of intelligence.

Brian distinguishes between "reckoning" -- the kind of computational prowess that enables AI systems to win gold medals at math competitions, and to write complex code -- and "judgment": a deep, caring commitment to the world that enables ethical action. (3/4)

Bibliography cleanup is known to be harder than AGI. Same with successfully connecting a laptop with a projector. It's what we humans will be doing long after the robot takeover. ๐Ÿ˜‡

An Artificial Intelligence Developed Its Own Non-Human Language When Facebook trained chatbots to negotiate with one another, the bots made up their own way of communicating.

Anybody remember this from 2017?

AI agents now have their own Reddit-style social network, and it's getting weird fast Moltbook lets 32,000 AI bots trade jokes, tips, and complaints about humans.

harcx Verify .bib file citations against academic databases (Semantic Scholar, DBLP, Open Library)

My UCSB colleague Gurusha Juneja wrote a python tool to auto-check your bibtex for hallucinated citations: pypi.org/project/harcx/

It supports papers, books, and

Usage:
