Beside, that we actually know by now nothing about the film, I have to say, that this scene at least tries to explain David´s megalomaniac flaw, or better said, his way to overdo human morality and ethnic standards, as his creator, Weyland is heavily flawed and far from being an altruist and philanthropist.
And for the folks, who wonder why Wehland is back in this movie, it is a flashback scene in David´s thoughts , most likely blending over to him standing in his studio amongst his creations.
