Glen,
The issue is not whether people see things or not, it's whether they come to fruition. This discussion has similar undertones to the one about invention, ala, "I invented that WAY before the patent got issued." So, there are plenty of game changers, but only some of them will survive.
We have a minor discussion going on at work about spectral analysis, wherein one faction wants to use a small number of samples and interpolation to the rest, while another faction points out that absorption spectra tend to be "spiky" and therefore un-interpolateable.
This is likewise the case with innovation. The apocryphal story about Intel's marketing guys poo-pooing the microprocessor because there were only about 16,000 annual minicomputer sales worldwide illustrates the point that predicting cataclysmic events is extremely difficult.
Companies would dearly love to be able to predict which technology to bet on; I know mine would. But, in many cases, until the technology actually exists and gets used, the problems it can actually solve are unknown. After all, how many "answers looking for questions" are out there?
In answer to the other posting, innovation is still being done, otherwise there would be no new patents; we just applied for a patent on a solution to a problem that has been around for 50 years, with numerous attempts and patents on previous solutions.
Claude Shannon supposedly said that you cannot "solve a problem before its time," which also points to the fact that you cannot predict a solution if you don't even know there's problem at all.
Many of the current cryptographic algorithms could not have been invented until there was a need to improve on older approaches because of flaws or technologies that make the older approaches obsolete.
Likewise, even 20 or 15 yrs ago, few people would have considered the possibility of using graphics processors to solve mathematical problems. I will confess that while I recognized that the processing power of the graphics cards in my computer exceeded that of the main processor, it wasn't obvious that the power could be harnessed to tackle non-graphics problems. And it's not even clear that the graphics processors from 15 yrs ago could, since they were purpose built for a specific application. Undoubtably, someone attempted to solve a similar problem and posed the question back to the designers, who were then able to see their way to a more general purpose architecture that could be applied to a larger class of problems.
