Crazy to think that there will come a time when we can't even see anything beyond the local group, let alone travel there.
For this reason our current knowledge of galaxies beyond the local group must be preserved not merely for future generations, but for all future intelligent life in the Milky Way. We have to a) not wipe ourselves out and b) not lose the data we currently have and are recording and c) take copies of the data to other star systems before the death of the Sun.
