On: Upper limits on partial Dyson spheres in the Milky Way

[buryat]

what would prevent an intelligent civilization from covering all other stars in dyson spheres?

and the dark matter is everywhere (almost, there're galaxies without it) which would mean that most of the universe has intelligent life but then why there's no other signals? something should've leaked/pointed at it

[ncmncm → buryat]

What would prevent it? Good sense. To be able to do it is to know better than to bother.
