An entity that isn't bound by human vulnerabilities could go places that humans either can't (or really don't want to) go, like planet Mercury. It could send us abundant building material from Mercury to build moon cities and orbital colonies, then abundant carbon dioxide from Venus to help pressurize them.

All the sci fi guys want to write about traveling to other star systems, but the one we started with is remarkably good. If we can make a robot-ship to siphon gas giant atmospheres we could hypothetically build giant fuel refineries to power primitive interstellar ships, but also fuel for traveling between solar system colonies to continue massive human growth.
