I’d describe it more as optimism than happiness. You gotta believe in the future vision, how great a place this is, etc.

The hope is that it creates a can-do culture. Downside is that it can create a culture where no one feels safe criticizing bad ideas.

It’s possible to deliver criticism in an optimistic way, if it’s impersonal and concrete (according to M Seligman). BTW, that’s also a standard for academic criticism. But there is a difference between allowing only optimistic criticism and banning criticism at all. That’s the problem with both tech culture and academia these days.
