Tallying these, it looks like roughly one in six have actually come true. Another one in six seems likely to come true in the readily-forseeable future (say, five to eight years). Note that many of these depend on what you’re willing to call a “computer”. I contend that just because something has a microcontroller running it doesn’t make it count as a computer; e.g., a traffic light doesn’t qualify. But, should a cheap-ass dumb cellphone count? I think a certain amount of user-mediated flexibility should be a requirement, but ultimately it’s a semantic argument anyway...
One weakness is pretty clear—excessive optimism in the speed of development/adoption. There’s no technological barrier to doing most of these things today, or in 1999 for that matter (although the robocar seems to be following the flying car along the path to perennial futurism). The most obvious problem is economic: at what point does the price come down to the point where it’s worth bothering?
However, the less obvious problem is that many of the predicted technologies are simply not as practically useful as they sounded like. Speech recognition (the topic of multiple predictions) is in fact the perfect example of this; dictation software has in fact improved immensely since 1999, and extremely accurate commercial software is available today. However, the market for it is small (outside of niche markets like phone hells), and shows no signs of explosive growth.
The sad fact of the matter is that, technological wizardry notwithstanding, when you actually try out speech recognition, it is less useful for everyday tasks than a keyboard, for most people and purposes. The same kind of problem is encountered, to varying degrees, by virtual reality, haptic interfaces, educational software, and e-books, among others.
Finally, I don’t contend that all of these functional deficits are irremediable; just that there is no particular evidence that they will ever become practical, and at any rate a great deal more work would have to be done to make them so. And the moral of this story, I think, is that it’s easy to grossly underestimate the friction that engineering problems generate. So, when you’re worrying about a hard takeoff from nanotech or whatever, bear in mind the modest fate of Dragon NaturallySpeaking.
