Hmm I hadn't looked at the Drake equation.

It is interesting to note L, the life time of the species or how long you can notice a species. For a dyson sphere blocking the light of a star we would expect it to block for the life time of the star. And if you are making that large you have to make all the other terms a lot smaller than the estimates there.

Or were you thinking of a more realistic equation?

A colonized civilization that still had contact between its various planets could still be wiped out by a plague or a sufficiently widespread war. Or they could commit mass suicide. Or they could be attacked and killed each and every one by another alien species. Why are you making such confident, general statements about a huge potential class of forms of life you have not met?

Even if thats the case it just means that L is dominated by probability any given civilization gets to the level of colonization. Plenty of civilizations could destroy themselves first.
