That's basically my view. It probably takes a long time for intelligent life (or intelligence in a form we are able to recognize, anyways) to evolve on any planet. If we don't see signs of it, it must be because the universe is still too young (and considering signal from a planet a million light years away won't arrive till as many years pass). Millions of years from now, one will be able to scan the heavens and find signals of tens of thousands of far-off civilizations.
