It's cool they've developed some tech to clean up signals, which could be useful elsewhere, but searching for extraterrestrial intelligence is a complete waste of time and money.
As Fermi proved long ago, if we were going to make contact with extraterrestrial intelligence, we should already have done so many times over.
It's just a numbers game. Even at 10% of the speed of light, an intelligent species could colonize the entire galaxy in less than a million years. Given that the galaxy is over 13 billion years old, and it only took just over 4 billion years for intelligence with the capability of space travel to arise on Earth, If the probability that intelligent life arises on a planet other than Earth is anything other than zero, it should have already happened over and over and over again in the history of the galaxy. As the SETI people like to say, with 100 billion stars in the galaxy, and 14 billion years to play out, any non-zero probability of the existence of extraterrestrial life means it is definitely out there. What Fermi says is, sure, in that case it should be EVERYWHERE, so where is everybody?
The fact that we see no evidence of this means that for some reason intelligent life does not spread throughout the galaxy in a way that is detectable by other intelligent life. It doesn't mean it's not there, it just means we will never detect it, because if we were going to, we would have done so by now, given the age and number of stars in the galaxy.
And before anyone starts posting "objections", Note that virtually every objection to the Fermi paradox only proves the paradox when you think about it.
Maybe all intelligent life destroys itself in a great firewall? You've just proved the paradox.
Maybe all intelligent life develops to a point where they communicate by means that are undetectable by us? You've just proved the paradox.
Maybe all intelligent life decides that colonizing the galaxy is not a worthwhile pursuit? You've just proved the paradox.
Maybe intelligent life is so exceedingly rare, that even with 100 billion stars in the galaxy humanity is the only intelligent life? You've just proved the paradox.
Sad, since I'd love to meet ET, but unfortunately it's the reality of the numbers.
(By the way, I am aware that there is some doubt as to the provenance of the Fermi paradox.)
