Personally, I don't believe in the great filter hypothesis. The universe is incredibly vast enough entire civilizations can likely go through millions of years of births and deaths without ever having contact with another alien life form. Humans have a huge bias to feel "special".

We've only been broadcasting radio waves for a few decades now, and even that would just be lost in the background noise at large distances.

It would be extremely surprising if we even find any life outside the solar system for at least a few centuries.
