Pretty sure this means radical and revolutionary in the political sense. Though most scientists and astronauts weren't billionaires - they were government employees.
Yep. The race to the Moon was just a dick measuring contest between the US and USSR. Manned space travel is a meaningless ego trip for governments. Unmanned space travel is equally useless in practical terms - learning about other planets does nothing to help the proletariat on our own - but at least wastes less money.
Global internet connection via satellite, and GPS, on the other hand, have helped the proletariat in actual practical terms. It's a shame it took all that billionaire ego dick waving to get there.
I sense sarcasm, but you are literally, unironically, correct.
If faster than light travel does not change the material conditions of the ordinary person, then it's not radical or revolutionary - it's just another toy for the rich and/or dick measuring tool for governments to boast about.
I think you're using those words differently from how people usually use them. Because most would consider FTL travel a pretty radical and revolutionary breakthrough lol
There is a but of truth in that. But FTL travel may reduce costs due to formerly inefficient due to distance sources becoming plausible. Even if it is not available to the average Joe. A lot of advances in tech reduced the distance of objects e.g. ships and carts.
China invented a few electric cars that are just as good as a Tesla for 1/3rd the price. Our benevolent plutocrats responded by putting a 100% tariff on Chinese electric cars.
