Well, in all fairness, the people of Earth had solved all their problems, but the rest of the galaxy still needs us Hoomans to fly up on their systems and give them the what-for on the higher moral standard.
Well, my issue with it has to do with what we humans tell ourselves about our humanness, not about what any other species turns out to be like. How will we treat that species if we're still sitting here stewing in fear and ignorance and bias? Will we have gotten past our self-ignorance enough to have the wherewithal to defend against unexpected alien behaviors? Will we just remain stuck in this infantile, black-and-white mythology of us vs. them, good vs. evil, drumming up enemies and wars indefinitely?
I'd like to think not. To continue the Star Trek "philosophy"... the cause of the end of human tribalism was twofold... firstly, the discovery of warp drive introduced us to a galactic community that changed our perspective... hinting at a loss of religiously self-centered thought.
Secondly, the invention of the replicator caused a mass distribution of resources. "Having things", like food, water, and everything else because trivial. Economic systems went extinct. The purpose of being was not to accumulate things or power to get things, but instead to enrich oneself in knowledge and share capabilities and ideas.
