It's hard to believe that every civilization would advance at the same rate.
Therefore, there might be races out there less advanced than us - and races
more advanced. Three hundred years is not a millionth of an eyeblink to the
universe. If there are other races out there, shouldn't some have become
sufficiently advanced by now to have found us?
This is all speculation, based, as someone said, on a single data-point.
Still, it does bear some thinking upon, does it not?
But the problem is that Fermi's paradox is that it assumes that FTL (or FT communication) is possible. Given what we know about physics at this point in time, it is impossilbe. If there is no solution to this technologic problem species more advanced then us will not be trying to communicate (or not trying that hard). They may be in space; they may be colonizing other worlds but given the vastness of the universe they may be very unlikely to run into us anything else intelligent.
