To any one person, sure. But, as the saying goes, "None of us is as dumb as all of us."
Once you start move into the realm of group decisionmaking based on hypothetical future demand for $OUR_WORLD_CHANGING_PRODUCT, positivity culture starts to take over. Plenty of people in the room where the decision is made may be thinking, "But what if this is a passing fad and people don't really love our product in any sort of durable way," but nobody wants to be the one to actually say it.
I would even go so far as to say that those whose temperament would allow them to say something like that out loud in the boardroom generally don't get promoted into the kinds of positions that get you invited to boardroom meetings.
Positivity culture exists because there’s no real downside for the people exuding it. You swing for the fences and the losses and layoffs are someone else’s problem. Most decent people might find such decision making distasteful and that excludes them from leadership.
It's sort of like optimistic concurrency. Sure, transactions straight-up get killed on a regular basis. But if you make transactions cheap things that are easily replaceable, then the overall system might still benefit.
I think that all you really need to do to translate the principle to business culture is replace the word "transaction" with "someone's career".
It is also because executives operate on the long tail of a pareto distribution. You get there by capitalizing on a large number of successful gambles. With few exceptions, you don't get their without beating the odds several times in a row.
