Yeah, we only landed a couple rovers on a #^$%ing asteroid, no big whoop.
Set against the Holocaust and repeated other mass killings and horrific cruelty, causing the extinction of multiple species, probably screwing up the planet's climate, spreading plastic to the deepest part of the ocean, not to mention inventing and producing vast numbers of weapons capable of wrecking the planet? Yeah, sure, a bit of precision littering on a neighbouring rock cancels all that out. Hurrah for us. We're the bestest species ever!
Any moment now we'll work out a way of organising large groups of people to get along without constant conflict or massive collective-action failures. After all we are good at manipulating physical objects, social organisation can't possibly be harder than that, right?
My real point is simply that we just haven't been here very long. The dinosaurs were around a _lot_ longer. Far too early to call us a success or to conclude our enlarged brain is a survival trait. The jury is still out...at best.
