I have a friend who is doing stuff with it, and he's incredibly excited about it, which is definitely a good sign.

I was really excited about it at launch, but its proprietary nature put me off.

I tried, also all a little while ago, really found the puzzles fun to do and then tried to implement some basic radar pipeline things and found lots of just basic 'building blocks' for signal processing (i/o things, fft) were missing to the point I went back to JAX.

I'm still not manage memory on GPU the way I would like, but mojo (or, my ignorant first stab at it) did not let me exploit direct DMA type things anyway.
