Were you *really* into Popular Mechanics growing up Mike?
Have you got your kitchen robot and flying car yet?
I hate to jump into the fray (no I don't), but I think The Flying Car, is already a reality, and it could be argued that with all the machines available in the average kitchen, when put together, they might qualify as, The Kitchen Robot. But in any case, that illustrates the point, that I think you're BOTH trying to make.
While these types of evolutionary (revolutionary) products, may someday displace the leading edge technology we have today, IMO, it may not happen tomorrow, or next year, or maybe even in our lifetime. So I have to say, that I think that "someday", there "could" be flying cars, and robots that take care of menial tasks, and most electronics based on light, but I agree with you, in that, I'm not holding my breath waiting for it to happen on Mike's schedule, unless "Soon" means that perhaps my "Grand" or "Great Grand" descendents will use them :-)
btw - I happen to like popular mechanics. It makes the dental office waiting room, a "little" more pleasant :-)
