They've already ceded the entire GPU programming environment to their competitor. CUDA is as relevant as it always has been.
The primary competitors are Google's TPU which are programmed using JAX and Cerebras which has an unrivaled hardware advantage.
If you insist on an hobbyist accessible underdog, you'd go with Tenstorrent, not AMD. AMD is only interesting if you've already been buying blackwells by the pallet and you're okay with building your own inference engine in-house for a handful of models.
