Well you’re right that it’s not practical now. By “soon” I was thinking of like 10+ years from now. And as I said, it would likely start in systems that aren’t used for those applications anyway (aside from web browsers, which use way more ram than necessary anyway). By the time it takes over the applications you listed, we’ll have caches as big as our current ram anyway. And I’m using a loose definition of cache, I really just mean on-package memory of some kind. And we probably will see that GPU style memory before it’s fully integrated.
