I've just finished reading "Extraterrestrials: Where are they?" by
Zuckerman and Hart. It really scotches the idea that SETI might
actually be successful, even though the Fermi paradox is a bit
overdone "Any ET civilisation  of substantial duration would have
colonised the Galaxy by now. So where are they?"
However, Gott raises an interesting point. Anthropic reasoning eg
Doomsday argument really rules out galactic colonisation - at least
for our reference class. It would appear that the Doomsday argument is
in direct contradiction with the Fermi paradox. I am rather
uncomfortable about this, and my preference would be to accept the
Fermi paradox argument over the anthropic reasoning.
Any comments?
