Yeah, but if you're thinking on those timescales you'd probably be better off using orbital telescopes, or telescopes located on other planets or moons with little to no atmosphere. Satellites and the commercialization of space will be important to enabling that level of space-borne infrastructure, so even in the really long run the utility of satellites probably still wins out.
