When have you ever been involved in a game changer tech stock that results in a simple pass or fail?

There will be unquestionable success ( in some areas ) that are marred by inconclusive results in other areas.
Such is that nature in new tech at production scale.

The question is how successful in $$s term is the result, and, how worthwhile is it investing more $$s in the tech to make the success factor commercially "viable".
There is much more water to flow under the bridge of success, or otherwise than just the MPA.
