I think Apple is going to make rapid and substantial advancements in on-device AI-specific hardware. I also think nVIDIA is going to continue to dominate the cloud infrastructure space for training foundational models for the foreseeable future, and serving user-facing LLM workloads for a long time as well.
If you're saying Apple is going to 'take on nvidia' in edge inference, then I don't disagree but I would hardly even count that as taking on nvidia.
It took almost a decade but the PA Semi acquisition showed that Apple was able to get out of the shadow of its PowerPC era.
Nvidia will remain a leader in this space for a long time. But things are going to play out wonky and Apple, when determined, are actually pretty good at executing on longer-term roadmaps.
