What you said makes sense, except;

have another in the wings to be rushed in for just this type of problem.

That is what I had in mind when I described Charlie and the burning power supplies. Always pack a spare!

"Charlie" in this case is honors of the "two Charlies" who accompanied the Wright brothers on some of their most crucial tests and public demonstrations, Charles Taylor and Charles Furnas. The Wrights experienced dozens of disastrous public demonstrations, ranging from the time the airplane did not take off in front of reporters (Dayton, OH, 1904) to the time the airplane crashed and killed the passenger (the official U.S. Army tests, Washington DC, 1908). They had dozens of other crashes and accidents. (By the way, the two Charlies were never to blame as far as I know.) If they had staked their success on a single demonstration they would have failed. On the other hand, it took only two successful demonstrations to make them the most famous people on earth in 1908.


If the device is so expensive or complex and borders this close to working
or not working then the public demo in my mind is only to get new money to
hold off the old providers (VC's) and get new cash to keep everyone quiet
for a bit longer.

I disagree. Marginally functional technology can be successfully demonstrated, but you have take the right approach and say the right things, to keep the stakes low in the event of a failure. Edison, the Wrights and many others screwed up demonstrations. Edison's early incandescent lights exploded and set fire to his parlor during a demonstration to investors. His wife, who was used to such things, put out the fire while redirecting their attention to tea and snacks.


Unless I have my history wrong, old Henry Ford did not present a lot highly
complex auto before he sold a working one. Think is was simple at the start
and grew in complexity.

Actually, Ford is a counter-example. He started by building a racing car, which was a complicated and finicky thing, and he won an important race. Auto racing was in its infancy back then, so no record lasted for long, but he leveraged his short-lived fame to get investors to put money into his plans for a simpler passenger vehicle.

I suppose if he had lost that race, he might have won the next one. But it was still a daring, all-or-nothing venture. There were not many races back then, and the drivers were often killed or wounded.
