Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and Ideas
Welcome to the February 2026 Ask Me Anything episode of Mindscape! These monthly excursions are funded by (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number -- based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good -- and sometimes group them together if they are about a similar topic. Enjoy! Blog post with AMA questions and transcript: Note that Mindscape now has a new hosting provider, . (Actually a return home, as that was my first host when...

336 | Anil Ananthaswamy on the Mathematics of Neural Nets and AI
Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and Ideas
Machine learning using neural networks has led to a remarkable leap forward in artificial intelligence, and the technological and social ramifications have been discussed at great length. To understand the origin and nature of this progress, it is useful to dig at least a little bit into the mathematical and algorithmic structures underlying these techniques. Anil Ananthaswamy takes up this challenge in his book Why Machines Learn: The Elegant Math Behind Modern AI. In this conversation we give a brief ove
info_outlineOur universe started out looking very simple: hot, dense, smooth, rapidly expanding. According to our best current model, it will end up looking simple once again: cold, dark, empty. It's in between -- now, roughly speaking -- that things look complex. I have been working to understand the stages by which complexity comes into existence, thrives, and eventually disappears. Without going into technical details, in this solo episode I give an overview of the general picture and the clues we are looking at to better understand the process of complexogenesis.
