The obvious answer to that is clustering machines of course!

Not unless when they sell dozens of millions of them.

To quote Linus: "The tiny processors have won".

Because they get massively produced which keeps price cheap.
It's about clustering them and then produce software that gets the  
maximum performance out of it.

The software is always a lot behind the hardware!
