Be careful making arguments of this type, Earl. Many thought that
Rotary Rocket, Beal Aerospace, and Teledesic were sure things because
wealthy men with impressive track records for making money such as
Walt Anderson, Andrew Beal, and Bill Gates were investing in them.
It's still the same old argument from authority fallacy.
