The space race did contribute to high tech development...of course.....
But so did the Cold War, Hollywood, medicine and the toy industry.
I contend that the high tech revolution would have arrived just as soon without manned space vehicles.
Once the horizons were extended for personal use of computer technology, the force of the marketplace took over.
Now it's government science that has to catch up and beg for new gadgets.
Well, you would be completely wrong, because you're basing it on suppositions instead of what actually happened.
Go ahead, do a little research. You might enjoy learning something.
Millions and millions of dollars were poured into the rather young microchip industry - spurring innovation MUCH faster than it would have without the space program.
Without the space program, money would have trickled in. The race with the russians opened the floodgates and jumpstarted the industry years ahead of where it would have been otherwise. And according to moore's law, what we would have been doubling from every 18 months would be miniscule compared to where it is now.
