The main goal of any species is to survive/reproduce.
We don't know if there's any other intelligent life in the universe, or how common it is. The one thing we do know is that we haven't found any.
There could be many reasons for this, and one of those is the Fermi Paradox (great filter).
Whether this is a real thing or not we don't know, but by establishing sustainable settlements in space, we hedge against the idea of us dying out via ourselves, asteroids, etc.
If there are space aliens hanging around, they likely wouldn't contact us
Just seeing them would give us a huge technological leg up. Right now we don't know that interstellar travel is readily feasible, but if we did know that then it would suddenly make sense to spend 100 times as much on space tech
Considering what a bunch of jerks we are to each other, I don't think aliens would want us roaming around freely
Yeah, there's really no reason for them too. If they are able to do interstellar travel, resource harvesting (from asteroids, comets, moons, planets, and suns) is relatively simple.
The thing is, I don't think it'd matter technologically. I don't think a kardashev 1 civilization could ever catch up to a kardashev 2 civilization.
Maybe once they've reached a "technological plateau" it becomes mutually assured destruction? But instead of nukes, it's targeted gamma-ray bursts? Who knows...
