Indeed, I agree. This is the dark aspect of the expansion into space. If you are interested, a good read (dry and terrifying) is Dark Skies:

It is very academic in its tone - but many of the scenarios he discusses are frightening (think The Expanse level threats). I tend to be more hopeful on this front. Hopefully the pursuit of economic prosperity nips military expansion, but who knows!
It's hard for me to be optimistic about anything these days.
