I'm not sure about that. NVIDIA seems to stay in a dominant position as long as the race to AI remains intact, but the path to it seems unsure. They are selling a general purpose AI-accelerator that supports the unknown path.
Once massively useful AI has been achieved, or it's been determined that LLMs are it, then it becomes a race to the bottom as GOOG/MSFT/AMZN/META/etc design/deploy more specialized accelerators to deliver this final form solution as cheaply as possible.
