SETI (the search for intelligent live in the universe) - NOT amateur radio

To the best of my knowledge this has been going on since the mid 1960s at least, without success. 

Now AI has been brought in to help data processing. According to the BBC there are potentially 10-50 billion places where intelligent life could exist just in this galaxy alone. 

There are so many variables like where do you look in the electromagnetic spectrum. Indeed, is this the best place to look? 

If we found signs of intelligent life, it could have profound effects on this small blue dot.
