I agree that eventually the smallest feasible "transistors" become commonplace. I agree that Moore's law, which I'm going to (mis)define as CPU performance, will eventually run out, but it will be some time off still. The major areas left to work on (that I can think of are): (1) Vertical integration (stacked chips). This would allow CPUs with something like the 1.5th power of how many transistors you can fit in a horizontal area. That's something like another 10 ~ 15 years of Moore's law. (2) Multiprocessing. Right now, only a couple instructions can execute at a time. Theoretical maximum is billions of times more parallel. I'm guessing that there is about 5 years of Moore's law available here. (3) Asynchronous logic. Synchronous logic really removes a lot of performance from today's systems. They are knocking on this barrier, eventually we'll be forced to explore it, and the improvement in performance is about equivalent to another 3 years of Moore's law. I'm guessing that another 25 years of Moore's law will "bless" us. At the end of that time, home computers will be superhuman in power. Right now, they're still dumb as planaria. While there are currently no uses for computers of that speed, I have no doubt that we will find stupid things for them to do. At the same time, I believe that the trend towards the average computer being cheaper will continue. That is, there is less and less reason to be on the cutting edge of computer power, and this will reduce the amount that each computer can be sold for. All this means, in terms of the increase in computer power over time, is that there will be a slowly increasing delay between when a new technology becomes possible and when it is actually implemented. This would result in a decrease in income to the computer design firms, but at the same time, the market is increasing due to the world's becoming wealthier. Consequently, I see a more or less stable industry (overall) for the next few decades. That doesn't mean that I think that the companies currently on top will remain there, just that the industry will still exist. -- Carl P.S. I think MU will be under $20 by a year from now.
