Thoughtful reply, but you're using a 'read too many hard sci-fi books' approach. 'Going there' is over-rated and is full of hazards, including
We have two future needs. One is to obtain knowledge and the other is to create backup worlds so we are not made extinct by the first, next,
IF we had, already in place, a 'map' of all the worlds of the M-W galaxy on a Galactic WWW, then we could quickly and efficiently look for a habitable
world that is not 'xeno-biologically' infested (an oft forgotten quality) and start to make a back-up Earth. But we don't. What is your plan, search
the vast M-W galaxy in chemical rockets or even advanced jump ships with 'crew'? That could take millions of years and even end up with a
mission-ending setback (like bringing home a plague!).
No. We need the information (using Von-Neumann probes with limits so they don't run out of control), and then with the information carefully pick and
start to craft backup Earths which are near enough to get to, but not so near that a GRB could take us both out (the folly with trying to make a back
up Earth within our solar system. A catastrophe to our Sun kills the whole system, for example).
If we had constructed such craft to simultaneously go out and probe and send back information as soon as we could have gotten into space instead of
spending vast sums trying to blow each other to bits, we'd be a bit further on by now. But alas, we are actually doomed, because we have squandered
our limited resources and will run out of money and resources by about the 2200s.
