These guys are not creators or inventors. They're hype men.

Yes, just like Elizabeth Holmes. Or Hwang Woo-suk’s stem cell cloning. Or the many “free energy” crackpots. Or the people promoting radium baths for random ailments. Or Tesla’s late-in-life claims about wireless energy, death rays, and cosmic energy. Or the myriad purveyors of “snake oil” and all manner of “tonics”. The list goes on and on.
