It's hard to say what nanotech will ultimately pan out to be.
I realize that chip fabs keep getting more expensive, but is there any reason to think this can't reverse?
But in the absence of nanoassemblers, it'd be a very bad idea to bet against Moore's second law.
r/Fitness does a weekly "Moronic Monday", a judgment-free thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. I thought this seemed like a useful thing to have here - after all, the concepts discussed on LessWrong are probably at least a little harder to grasp than those of weightlifting. Plus, I have a few stupid questions of my own, so it doesn't seem unreasonable that other people might as well.
