I wonder if Jensen is scared. If this opens up the door to other implementations this could be a real threat to Nvidia. CUDA on AMD, CUDA on Intel, etc. Might we see actual competition?
Abstraction layers for GPU compute already exist; this is yet another one, so it doesn't change anything substantially. Most of the time code written using such layers ends up running on NVIDIA hardware in prod anyway, so if anything that is a net positive for the company - it means that more people can now develop for its hardware on their devices.
