How do chips actually work – starting with basic logic gates, and working up to why GPUs, TPUs, FPGAs, and the human brain each look the way they do.
0:00:00 – Building a multiply-accumulate from logic gates
0:16:20 – Muxes and the cost of data movement
0:25:59 – How systolic arrays work
0:39:00 – Clock cycles and pipeline registers
0:51:40 – FPGAs vs ASICs
1:03:14 – Cache vs scratchpad
1:07:16 – Why CPU cores are much bigger than GPU cores
1:11:49 – Brains vs chips
1:15:22 – A GPU is just a bunch of tiny TPUs
Look up Dwarkesh Podcast on YouTube/Spotify/etc to watch. Enjoy!
When the Euphoria ragdoll physics engine was used back in Grand Theft Auto IV, Star Wars The Force Unleashed, Max Payne 3 and Red Dead Redemption, I thought this was going to be the next evolution
Then came GTAV which neutered the hell out of the ragdolls. In RDR2 it was passable but still left a lot to be desired.
Bodycam unironically is the only game I’ve seen that takes what the Euphoria engine did and vastly improve upon it and put it into a shooter. These are the ragdolls i wanted in Tarkov, Ready or Not, and any given hardcore shooter.

> Give people Opus 4.6
> People love it.
> For 2 months you degrade Opus 4.6
> You give back normal Opus 4.6 and call it Opus 4.7.
> People love it.
That's the business model.
