You should welcome a third competitor to the duopoly that has strangled CPU development. We surely could have made much more progress if x86 was not limited to only two (really three) competitors, you can already see how much change that AMD getting back in the game has made.
And I'm not sure Huang is going to burn it all down anyway. That seems like it would be a shortsighted move that would negatively affect the long-term value of ARM.
But I mean - I don't think anyone can deny that Huang would do great things with ARM. Terrible, perhaps, but also great.
(and it says a lot that a lot of people are probably nodding along with a comparison of one of the greatest tech CEOs of all time to literal Voldemort, the public opinions on NVIDIA and Huang are just ridiculously hyperbolic)
Plus CUDA shows what can happen even when alternatives are available (OpenCL for example) you just have to use the hardware / software integration to be sufficiently ahead and establish a virtuous circle.
This suggests that as a consumer, you haven't benefited from this.
The fact they own their full stack, has resulted in some of the most anti consumer parts of the business. Allowing monopolization on repairs / part pricing etc
I was pointing out that the above commentors personal experience showed otherwise.
