AMD funded a drop-in CUDA implementation built on ROCm: It's now open-source

It seems to me that AMD are crazy to stop funding this. CUDA-on-ROCm breaks NVIDIA's moat, and would also act as a disincentive for NVIDIA to make breaking changes to CUDA; what more could AMD want?

When you're #1, you can go all-in on your own proprietary stack, knowing that network effects will drive your market share higher and higher for you for free.

When you're #2, you need to follow de-facto standards and work on creating and following truly open ones, and try to compete on actual value, rather than rent-seeking. AMD of all companies should know this.

I don't know about that. You could kinda argue the opposite. "We improved CUDA. Oh it stopped working for you on AMD hardware? Too bad. Buy Nvidia next time"
