Is There a Need for Aliens to Take Over the Galaxy?

My favorite theory is that we have a false assumption that the best thing to do as an alien is or any species is to take over the galaxy. That actually if we reach a certain level of like I don't know techno utopia technological advancement that it's better to just like make life on one planet awesome and so you could do that in a number of ways. You can imagine a world like the matrix would recreate like a digital world where you could plug into and it's essentially just as good if not better than the real world, he says.
