(I'm trying to do 3D stuff in Rust. The number of people who do hard 3D stuff in Rust seems to be very small, which is frustrating. There are many obscure bugs in the graphics stack and not enough people to exercise the stack, find the bugs, and get them fixed. 3D game dev in Rust is below critical mass. Retro-looking 2D is doing fine. But most 2D Rust work could be done in HTML/CSS/Javascript, or could have been done in Flash.
About half of my time goes into graphics stack problems. This is not fun.)
