Quote from my past posts [1] on this point: > It's impossible to predict what tech can come out of such efforts that will be of use here on Earth in the future. The amount of money going to space exploration is peanuts so I think it's well justified if it has even a trace of potential to improve future of humanity and that has been true historically - e.g. satellites (GPS, weather, etc), medicine (MRI), and whole bunch of NASA spinoffs and more. > I think SpaceX to date has received less than 10 billion (say 20 to be safe) in total for everything! That's 20 years of research, development, coming up with never done before re-usable rockets, etc. > People spent nearly half a trillion dollars (not billion) on cosmetic products in a single year! You want to point fingers, point at something you can actually locate. Money spent on space is negligible to the point that it doesn't even warrant justifying spending it.
