However, I also feel that 'general' tech programs are warranted and that to a large extent, the space program fills this need. I do not see the two things at odds with one another either.
They're at odds with each other with regards to competing for funds. If there's gonna be a pie-in-the-sky technology push, and if the bleed off technologies are the benefit, then it might not really matter what you push for (in the 'longshot' category). It just has to be nearly impossible.
BUT, that's only with regards to the bleed-off technologies. The 'sure thing' technologies
will happen, so it's a question of what those technologies are.
There's also a very serious questions whether these NASA technologies were 'low hanging fruit' in a social sense. Were they the invention of fairly 'simple' physics that would have popped up with other types of technological pushes?
That said, I'm pretty on your side. I don't know whether it's better to create a society than creates billionaires, and then let them push for these things, or whether these things deserve tax dollar investment. In the 1960s, only the national superpowers could afford such things. Is that still true.
Are you suggesting that's the only place innovation spending and social spending come from - from companies?
No, it's not the only source. It's the major source, but it's not the only source. And they don't even do it very efficiently, since they're merely shooting for first order effects. They're only trying to create stuff that the customers want, which doesn't allow very efficient thinking.
An important thing to remember: it was the Space Program that put up the GPS satellites, but it was Sony that created the phone that lets me really benefit. What seems to work really well is the idea that 'the people' create infrastructure that 'entrepreneurs' then use. Create highways, and the trucking companies will come, I guess.
But, to go back to investment: the private corporations can really underinvest. We see this in neuroscience all the time. There's been a massive dropoff in neuropharmacological research, because "it's too hard and doesn't really pay". I mean, it's true, it's hard and it doesn't pay. It strikes me that 'giving up' ain't the correct social answer even if it's the right corporate answer. We need, very much, all of these technological breakthroughs in neuroscience, because (well) people will die horribly if we don't cure these diseases.
But the space program is cool, it produces astronaut-heros that a lot kids do idolize and emulate even if they wind up becoming doctors instead of astronauts.
There is that, and I don't think we can ever get back that flash. Like it or not, people got
bored of the Moon landings, and we've gotten somewhat blase regarding a lot of scientific advances. Most parents cannot answer the cliche childhood question "why is the sky blue?", so learning more about more exciting things about our solar system doesn't trigger their fancy either.
That said, I'm broadly on board. I'd like to see us become a space-faring species. I also think that "it's basically inevitable" at this point. Does it matter terrifically if we launch our first inter-stellar probe in 2050 or 2150? It matters if
it never happens, but I don't think that's likely.
Pending economic or ecological collapse of course.
Ironically, as science and things like robotics appear and advance, there's less jobs for people (and we're not just talking about menial jobs like assembly line or etc. There's replacements for fighter pilots, firemen, garbagemen and others).
I call this 'automation induced unemployment', and honestly I think it's A Real Concern. People seem to think that we'll just see the regular ol' Creative Destruction ("there are no buggy whip manufacturers any longer"), but I think that the velocity of job loss can accelerate well too fast for people to find alternative employment.
If the cab driver loses his job, if it's cheaper to make a robot to do his 'next' job than to train him, then he cannot get that job either.
I see no solution other than intentional redistribution schemes.
I think this is an example of how money ruins things. There's no reason humanity can't work on getting to Mars and helping the poor. Money is an illusory boundary.
Money is, labour isn't. If I'm using my labour to 'hire' people to bring me cigarettes and beer and to make me movies, then the poor people cannot 'hire' those people to help them.
