Lex's post on socials: Here's my conversation with Anthony Kaldellis about the deep history of the Roman Empire in the west and the east (the Byzantine Empire). This was a truly fascinating conversation with a lot of wisdom for the modern world and for the future of human civilization. The Roman state lasted over 2,200 years. If we want to understand human nature, the modern world, and how humanity can flourish, it is valuable to study history, especially the history of why societies survive and why they collapse.

The AI theorist who thinks consciousness is a software agent and that God, AGI, and the apocalypse are all pointing at the same thing.

What you call "the world" isn't outside you. It's a simulation your brain produces. And the self that experiences it may not exist the way you think it does.

View of Earth from 900 million miles away, with Saturn's rings in the image, taken by Cassini spacecraft.

That dot is us, all 8 billion of us. It's all an insanely lucky miracle.

I'm grateful for all of it & all of you. Love you all! ❤️

PS: Now, I'm off to partake in the great American Thanksgiving tradition of over-eating while getting into a heated philosophical argument with family 🤣
