I know a con when I see it. The same videos. The same narrative based on nothing but speculation. This amounts to "I want to believe" even when no proof is given.
Most of the 'new' and 'shocking' video looks like amateur cgi. Nothing in the narration presents proof, only speculation.
The key is the legacy programs that date back to the 1940s.
The current stuff is the shiny objects to keep you confused.
