I wouldn't fret too much about it. That paper is complicated
mathematical guesswork.
We have no evidence outside of our solar system. We have no facts
about what the likely probabilities might be.
Multiplying estimated ranges of probabilities is still guesswork.

But any other civilisation is indeed likely to be a long way away from
us and the light speed limitation will make communication very slow
and physical contact would take hundreds of years. We would have to
send an AI to represent us. Let's hope it doesn't tell the truth and
let them know how terrible humanity is!  ;)
