A technological lead isn't the same as a monopoly. Samsung and Intel aren't so far behind TSMC, in the grand scheme of things.Taiwan's monopoly on chips, motherboards and many other electronics is bad for everyone.
As for motherboards and such, most of the actual manufacturing happens in mainland China, but also some in places like Vietnam and Thailand. There are Mainland Chinese brands, also, but they're not sold in the US.
I found it interesting that Raja Koduri mentioned working with Indian graphics card makers, in the future.
LOL.It's bad for human development worldwide.
