What if the great filter of humanity is to overcome it's own nature that made it the dominant species of the planet and what if that is the universal great filter that makes the cosmos silent
I don't know if this theory has a proper name but I have seen it multiple times.
If a species has the ability to push their technology to the point they could become a space faring species, that technology will destroy the civilization before it can get there
It may depend on the rate they get to that point. Add in a dense energy source that's suddenly available and the rise of tech may be lethal. Perhaps the lucky ones don't have something like petroleum so their species matures long before they ruin their world.
I don't know about the end result under the same extremes. I do know that silicon life, while not impossible, it's probably unlikely. Silicon does parallel carbon in some ways including a similar location on the periodic chart (which is why it got attention from scifi writers), but the issue is simply silicon is nowhere near as "greedy" as carbon bonds.
