A little touchy, eh? My point remains that there are plenty of ways for the government to accomplish the supposed objective of preventing these engineers from defecting to China, and far more simple explanations for the plane’s disappearance, than the covert realization of the dream of teleportation.
You’re speculating about what the government might or might not do. That’s not the same as actually understanding his arguments and sources, and picking out the ones that seem incorrect or unsupported.
I get that this sounds like sci fi. I get that over the past few years we’ve learned to be skeptical about just about everything. All I’m saying is that if you actually took the time to review one or more of his videos, you might change your mind.
