I felt like Alien: Covenant was written for me and I will eventually watch it more than Prometheus.
David was everything the humans could provide in a single, refined package born from decades of Weyland acquisitions. Black goo mutagen was described as the same thing for the Engineers with "Through the virus / Xenomorph as glorious synthesis and poetic culmination of the species."
So, David is the human's form of Engineer mutagen amassing every skill of a species into a synthesized product. Humanity (Weyland) had pulled together the best resources and attempted to reach beyond our circumstances with David. And the humans will pay for their overconfidence.
I tried hard with that above Thoughts_Dreams. Are you now going to buy Alien: Covenant?
I can enhance more screen shots to try and pump you up.
