Finally bought the 4-volume set of Susskind's Theoretical Minimum series, the 1st of which, along with @stevenstrogatz.com's Infinite Powers, inspired Why Machines Learn, giving me the courage/desire to write a "popular" science book that embraced some of the hard stuff (equations/theorems/proofs).

When I proposed WHY MACHINES LEARN in Oct 2020, to my then editor Stephen Morrow, @carpenter512.bsky.social, I was sure he'd say no to a book full of math & equations. But he saw something in the proposal that even I hadn't and said yes, and I'm grateful for that! Got to thank him today in person.

Everyone is talking about DeepSeek's impact on industry. But another huge impact is the leveling of playing field between academia and industry: if these efficiency numbers bear out, then academia can both use LLMs and study/research them at scale!

This lecture is primarily about how animal brains have evolved, but in so doing Paul Cisek helps illuminate why artificial intelligence based on large-language models is fundamentally insufficent in reaching anything resembling human intelligence (perhaps even lampray intelligence).

A gentle reminder that you should always resist the temptation to tag a creative person into a negative review of their work. It doesn't matter what your intentions are, it's kind of an asshole maneuver. You are free to say whatever you like, of course. Making it their problem, however, is not kind.

Why Machines Learn: The Elegant Math Behind Modern AI – Anil Ananthaswamy
A rich, narrative explanation of the mathematics that has brought us machine learning and the ongoing explosion of artificial intelligence. Machine learning systems are making life-altering decisions for us: approving mortgage loans, determining whether a tumor is cancerous, or deciding if someone gets bail. They now influence developments and discoveries in chemistry, biology, and physics—the study of genomes, extrasolar planets, even the intricacies of quantum systems.
