Let’s just say what it is: devs are too constrained to jump ship right now. It’s a massive land grab and you are not going to spend time tinkering with CUDA alternatives when even a six-month delay can basically kill your company/organization. Google and Apple are two companies with enough resources to do it. Google isn’t because they’re keeping it proprietary to their cloud. Apple still have their heads stuck in sand barely capable of fixing Siri.
