An ET with a tech equivalent to Earth 200 years from now would
probably live in a society in which time and energy were both very,
very valuable relative to their value to us. The energy that we use
in a single househould might provide life for millions of
human-equivalent beings. The time in a single Earth day might be
equivalent to a human lifetime to them.
If so, space travel would be very, very unappealing. Imagine the
government saying, "All right, we need to kill a trillion people in
order to get the energy to launch this spaceship, which has a small
chance of colonizing an insignificant, poisonous, mineral-poor chunk
of rock a billion years from now." That's the proposition space
travel would be putting forth.
