About their creation? Yes as most of inventors about their invention usually

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.

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