You keep making these assertions, failing to back them up with anything other than hand-waving in the direction of entirely unrelated programs. You then respond to requests for citations, or even just an elaboration, with the near-verbatim ‘do your own research.’

Chiefly, how does that further the conversation? More pointedly, why should we listen to you?

Credentialism in this arena is valid, and what I currently see are multiple subject matter experts, albeit with a bias/incentive towards believing in themselves, versus you. Please substantiate your claims, or word them more carefully as to reflect them being conjecture.

Huh, I heard the same (tinfoil) argument about climate change, that all scientist make up the crisis to keep their jobs/funding.

Scientists are not the ones making the big bucks on fusion demonstrator construction. But, obviously, somebody is. Are. Every cent of overrun goes into a pocket. None of it evaporates.
