It doesn't enlighten anyone, sorry. You have good points, but the standing issue is that we know nothing of the travelers intentions or really anything about it. Why would it help us? Best case scenario would be that it hopes we can end it's age long war with the darkness and pretty much used us. Or maybe it is legitimately trying to help and the story is as cut and dry as it seems so far, and the darkness is malevolently chasing the traveler. We don't know. You're spewing as many theories around as game theories did. The only facts we know is that the traveler came, gave us the ability to skyrocket our civilization into an golden age only to be subsequently collapsed and brought down to its knees to a point where humanity is nearly extinct, brought on by an incomprehensible force labeled as the darkness that's purely chasing after the traveler. We're merely bystander casualties in the age long war. The traveler knew the darkness was chasing it, so my question is, why would the traveler purposely put billions of lives at risk if he was just trying to help? Why not stay away from civilization and fight his own war?
