A main component of the paradox is time, but this paper solve that. Life existed from the beginning, but only now has become complex enough. So, we don't see or hear artificial signs in other galaxies because light is from the times when there was not complex life in the universe. Now, we only have to solve why we don't see or hear artificial signs in our galaxy. But the problem is not so perplexing because we are talking about one or two million years. If, for instance, a big part of the galaxy is bad for complex life (after all, we are far away from the center and that could be relevant), Fermi's paradox is solved.

What are the odds that our life is the first that has reached sufficient complexity to be able to communicate within our galaxy? Given that there are 100-400 billion stars (and even more planets) just in the Milky Way: Pretty much zero.

  I appreciate a good reason to think deeply as much as the next person ... but odds are just that, odds. If we were the result of some freak black swan event that kickstarted "life", the odds of it happening are irrelevant ... because it did. To be clear, I'm not saying that's what it is ... the fermi paradox is a great thought experiment. But let's just keep things in perspective. Low odds don't mean something won't happen, just like "true random" doesn't mean the same song can't/won't play 10 times in a row ;)

    The troubling thing about the Fermi paradox is that the Great Filter may still be ahead of us. As in, the universe may be littered with the ruins of single-planet civilizations slightly ahead of our technology level. We may have observed and cataloged many such planets, failing to notice the ruins.

  The problem has been always the temporal scales. But if you change that, the odds are not so bad. If all the civilizations started more or less at the same time that us, it's not so weird that we have not found anybody else. If you add some other factor (maybe civilizations are only possible far from the center, so there is a big spread between them) the probabilities improve. It also would mean interesting times ahead for humanity. Of course, all this is only idle speculation.
