Yeah GPU compilers will be used for way more things than AI because parallel = good

Moving my thumb across the image causes the ball and cube graphic to disappear to black and then scrolls the page. Firefox on iOS

> the thing JAX was truly meant for: a graphics renderer<p>I mean, just like ray-tracing, SDF (ray-marching) is neat, but basically everything useful is expensive or hard to do (collisions, meshes, texturing etc.). I mean mathy stuff is easier (rotations, unions/intersections, function composition, etc.) but 3D is usually used in either modeling software or video games, which care more about the former than they do the latter.

Pytorch is such a maddening mess of half implemented research features in a state of Heisen-deprecation, Jax becomes more appealing to me by the day.
