On windows, you forget that it wasn't the case historically that windows could run on ARM, and it took years for MSFT to make it work (hence it was a real moat), and now that it works it is a real threat to Intel's grip on the PC market. So it exactly proves my point that you want to know how locked in your customers are to your product.

And as Bezos says, your margin is my opportunity, and nvidia makes humongous margins right now. It will attract investments in competitors. And if a competing GPU is half as powerful but a third of the price, it will eat market shares and compress margins. Unless customers cannot switch, but I don't believe that to be the case.
