what subscribers say

“Razib Khan’s two part essay on Indian history is brilliant. While it’s long for a blog post, you’ll learn more about India than you would in many full length books.”

-Scott Sumner

“Bro, I’m really digging your newsletter!”

-Carlos D. Bustamante, Ph.D., MacArthur Genius

thank you for sharing this Steppe history. It’s absolutely riveting and so fascinating. I’ve re-read David Reich’s book which, thanks to your Substack and podcasts, has become a much less impenetrable read

-reader R.

I too have been [sic] haunted by the steppe... But I grew up in an ancient small town in India filled with temples and a sense of "glorious in the past but a dump today". I read too much. I too was writing my own steppe thesis in college. But I gave up because evolutionary biology got hold of me. I now sit by your feet like they say in Upanishad, and yearn to go back to my old times.

Why I hope you’ll join me

In an age of tip-toeing around corporate media sponsors, risk-averse editors and craven group-think, Unsupervised Learning is one more little island of open discussion, difficult but important conversations, deeper reflection, the odd dangerous idea and of course, unsupervised (and rigorously uncensored) learning. You literally will often hear it here first.
