im not pro-ai-bro but i gotta say some of the maths involved is pretty cool

That math isn't being discussed here, it's barely even discussed in the book! Frankly how often do you open an HN thread on the front page and see any significant technical discussion of anything other than coding? I find the times I see someone writing out equations and discussing fundamentals so rare and welcome as to be memorable.

Most conversation here is profoundly non-technical and never touches anything like "the math".
