Is it really necessary to send humans to those places just to get the knock-on benefits? Couldn’t we do those things directly, without going there?
It seems to me that, today, those who have the money to spend on these endeavors would only do so if there were perceived short-term benefits to themselves. That means they plan to exploit the resources, or increase their own power somehow.
I know the good engineers that make this happen are doing it for the challenge and in the pursuit of knowledge, and I know that’s why we poors support it, but that doesn’t “pay the bills.” What is the motivation behind the money? Why are they really doing this?
Yep, and as I said, the return trip with all the rapidly evolved super-geniuses would be the impossible part of the plan.
You can’t travel someplace else - experience say 100 years, and then travel back to your place of departure and have had only 20 years passed. That’s fundamentally impossible.
Have had only 20 years pass in the local frame of reference, not the frame of the evolved super geniuses. Thus everybody on earth gets to enjoy the benefits, if there are any.
