This is the best take on Fermi's Paradox that I've ever seen.

@jimsalter Even if the odds are minuscule, I would like us to attempt high-power focused radio transmissions to candidate systems that could detect us, on the chance anyone was there to receive us. #meti #seti https://mrflash818.livejournal.com/229959.html
@mrflash818 @jimsalter Our most powerful radio emissions would not become audible with our best receivers any further away than 10LY, a fraction of just this small galaxy. There are a lot of stars in that sphere but it's still infinitesimal in the universe
@mrflash818 of course. SETI is incredibly cheap, when you look at the risk to reward, even if it's unlikely to pay off.
