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?
It takes a few eggs out of our current basket and puts it into other nearby baskets, so as to avoid complete species failure if our original basket falls or gets dropped.
Not the most ideal solution, as we should really step out of our stellar neighbourhood to achieve lasting civilizational redundancy, but it’s far better than not taking any eggs out of the current basket at all.
Plus, incremental efforts in achieving civilizational redundancy always have better results than great leaps, both in terms of consistency as well as resiliency. Figuring things out a bit at a time is nearly always more effective than trying to solve everything all at once.
