The moat is thinning with everyone going directly to TSMC, but with Jensen you always feel like the next big thing could be captured by nvidia. Without him it seems the company can draw on its previous success for a few years until that moat is completely gone. Nobody is going to be able to make a call like baking CUDA for years while it has little returns.
