Bieeanda,
IF NOT FOR OUR CORRUPT GOVERNMENT OFFICIALS AND elected mis-spenders, we'd have the flying cars (they do exist) as well as many of the other predictions.
I resent not having the tech that was discussed when I was a kid, and all of us still driving computerized Model "A"s. Nothing wrong with the Model A, but frankly our cars differs very little from the overall design of almost a century ago. Softer seats, mp3 players, but same basic design. This flies in the face of reason.
For some perspective, the '57 Chevy and the SR-71 Blackbird were designed at about the same time. The '57 Chevy is an antique car, the SR-71 purportedly the fastest plane we have ever had. The ONLY reason we know of the SR-71's existence (actually the designator was RS-71) was a "slip" by then President Johnson leaking the name by mistake at a press conference and "SPELLING IT WRONG"!! Also the name Reconnaissance Surveillance implies that there were other (Combat?) versions of the same aircraft, which have never been seen publicly. The SR-71 differs so much fundamentally from commercial plane that side by side on the ground they look as similar as apples and oranges.
Willing suspension of disbelief aide, what has ALL the tax money that has been spent for the past 50 years gone for???? I suspect there ARE many innovations sitting somewhere because they are:
a.) Are extremely cheap, durable, and last for a long time
b.) Would offer the public freedom from oil and government control, and
c.) Have the capacity to improve the quality of life without government assistance.
I have become very cynical in this respect as I do believe that as a society we are being controlled and kept at a "maintenance level” not allowed to experience fundamental change in technology or advancement by a bloated bureaucracy that feeds on it's own incompetence.
