I have a relative that worked at both Los Alamos and Sandia Labs.
He knew I was into this kind of stuff, but was appropriately tight lipped about it. He would go on about declassified things like the Atomic Airplane project he once worked on, but not a peep about classified projects.
We got into a discussion about Tesla’s stuff that was obviously making him uncomfortable. When I persisted he said..
“You’re into science fiction, right? Think about where you “think” we are, add 100 years, and you’re just getting close.”
Think decades of off-books and black project funding and it does not seem unlikely that a totally separate society has been created - one we know nothing about. Which if we saw it now would look like magic.
I’ve seen the “100 years” quote many times before. Thought it came from a retired Lockheed or Skunk Works executive.
