I’m not sure what point you’re trying to get me to concede. I’ve already stated that I’m on the RISC side of the debate. If your point is that it’s difficult to keep doing this with x86, I won’t argue with you. But that said, the x86 teams have kept up remarkably well so far. How far can they keep going? I don’t know. They’re already a lot further than everyone predicted they’d be a couple decades ago. Nearly free transistors, even if not fully free, are quite useful, it turns out.
