It wasn't so long ago that people said computers would never play chess better than a good human player. Now the world champion can't beat the best computer chess programs.
And if you compare how people lived in,say, 1900 with today, well, there's no comparison. Planes, cars, electronic equipment, medicine, computers, smart missiles, etc., all with a sophistication undreamed of then, even by H.G. Wells.
Yes, there was profit motive (including paying off the govt bandits), but so what? Those things got made and distributed, so that now there is MUCH more free time and easier work than in 1900, when maybe 80% of the population led a hardscrabble existence on small farms.
So I would venture to say the inventions DID happen, and DID create at least a physical utopia by comparison (albeit with psychological and sociological problems, mostly brought on by idleness), and I see no reason for the trend to stop.
P.S. There ARE a lot fewer tellers in banks nowadays, only they aren't doing other things at the bank. They weren't hired in the first place.
