A 9-year-old named Kai (“The Quantum Kid”) and his mother interviewed me about closed timelike curves, wormholes, Deutsch’s resolution of the Grandfather Paradox, and the implications of time travel for computational complexity:

This is actually one of my better podcasts (and only 24 minutes long), so check it out!

Here’s a podcast I did a few months ago with “632nm” about P versus NP and my other usual topics:

For those who still can’t get enough, here’s an interview about AI alignment for the “Hidden Layers” podcast that I did a year ago, and that I think I forgot to share on this blog at the time:

What else is in the back-catalog? Ah yes: the BBC interviewed me about quantum computing for a segment on Moore’s Law.

As you may have heard, Steven Pinker recently wrote a fantastic popular book about the concept of common knowledge, entitled When Everyone Knows That Everyone Knows… Steve’s efforts render largely obsolete my 2015 blog post Common Knowledge and Aumann’s Agreement Theorem, one of the most popular posts in this blog’s history. But I’m willing to live with that, not only because Steven Pinker is Steven Pinker, but also because he used my post as a central source for the topic. Indeed, you should watch his podcast with Richard Hanania, where Steve lucidly explains Aumann’s Agreement Theorem, noting how he first learned about it from this blog.
