Two reknowned researchers, an astrobiologist and a planetary scientists, have bet a bottle of whiskey (hopefully a good one) over whether we will discover convincing evidence of *technological* life in the universe in the next 15 years: https://mindmatters.ai/2024/01/science-wager-extraterrestrials-will-be-spotted-within-15-years/

Per the two: "Our conclusion is that advanced extraterrestrial intelligent life (ETI) is either (1) extremely rare or non-existent in our galaxy or (2) these civilizations are deliberately hiding from us. No other possibility seems very likely."

I'm not at all sure that no other possibility is very likely. For instance, see Universe Today's excellent series on SEVENTEEN hypotheses of why we haven't yet detected intelligent life in the universe: https://www.universetoday.com/119727/beyond-fermis-paradox-i-a-lunchtime-conversation-enrico-fermi-and-extraterrestrial-intelligence/

Also, I'll readily concede there might not currently be many (any?) other advanced civilizations in the Milky Way, but our galaxy is a minuscule dot in the cosmos....

...which is why FTL will not be enough. We need wormholes!*

*also, I'm almost finished rewatching Farscape, and at this point it's All Wormholes, All The Time.
