@brian_armstrong Good lord.

funny that dwarkesh is getting shat on for saying something that's obviously true-this was the original gist of my "you have two years to accumulate capital until the music stops" meme. but now that ai equity has blown up the tech oligarchs are working overtime to squash dissent

new tax proposal: NPS-based wealth tax

if you‘re a billionaire and you created a product people love you get a wealth tax exemption

but if you run a company with terrible NPS like Comcast or you became a billionaire by (legally) scamming people (crypto, SPAC, etc.) you should pay a heavy wealth tax 🤷‍♂️

@miniapeur Hatcher? so dissapointed

[ExL @pixlExL]

@kchoudhu I just graduated and this was very much the norm in my math classes. None of the content was of value but I think the process of actually doing the PS was incredibly rewarding

yeah you know what fuck it. let's romanticize homotopy theory, physicists have been stealing the spotlight for ages. let's make an Oppenheimer about calculating homotopy groups of spheres

@ma20d016 @asd214lasf @miniapeur That’s my fault: I wasn’t aware there was a specific algebraic topology Munkres book: thought you were talking about the point set book that covers a bit about the fundamental group. Sorry, will have to take a look

[ExL @pixlExL]

@ma20d016 @asd214lasf @miniapeur Munkres is a great book, but it really only covers the absolute basics of algebraic topology. It barely covers homology, and completely omits cohomology. For those topics, Hatcher is (unfortunately) the best choice

[ExL @pixlExL]

@asd214lasf @miniapeur I studied at a math dept you would almost certainly consider serious, and this is the textbook we used. I don’t disagree, the book is horrible, but it really is the only option. The alternatives are that much worse

@DC_Draino Wow! I wonder how much money Trumps taken from Jeff Yass. Surely it must be zero

@ThePhDPlace I imagine most of the head researchers at xAI have PhDs

@sidcodes if i remember correctly the median score on the AMO is a zero. so this score probably puts R1 in the top ~200 high schoolers

don't waste your time studying CUDA or calculus. pytorch abstracts away both of these

instead, if i were you, i would train hundreds of tiny little models

train PixelCNN on MNIST. train an MLP to play snake. train a tiny language model on your emails

@hendrycks People somehow making this political is crazy. This is not because of "academic biases" or "left-wing media", but rather because RLHF is done in Nigeria, Pakistan, and other countries with cheap labor. Replies are exposing complete lack of knowledge on how LLMS are trained

[ExL @pixlExL]

@sidcodes I think its a book that really heats up as you go: by part 2/3 you start getting into it. It's difficult to get everything from it but it's a fun ride. Also many parts of it are (afaik) meant to be intentionally confusing, which definitely doesn't help
