Basically i think the premise of these old people transferring their brains or consciousness over to new hosts to be a reality
look at what the soviets were capable of back in the early 1900's
This idea of the elite dying off sounds nice but i think with the current tech they can transfer over their consciousness/brain to a new human host and live on ….
I think also having this movie show explicitly whats being done is used on the public to make them believe it can't be done because hey wasn't that in a stupid movie…
So maybe David Rockafeller however you spell it…he's not actually dead, he's living in some young black mans body
