Maybe. I tend to focus on "blockers," and things that can go wrong, first. I suspect a lot of people want to be buttered up, before the problems are discussed (i.e. "That's a really great idea! Have you thought about how often the hinge is stressed?")

I'm a bit "spectrumish," so I sometimes miss the niceties.

The Japanese were not reticent about discussing problems. It was fairly brutal, but we made great stuff.

Discussing and solving problems is different than firing off Thought Terminating Clichés to kill someone's project.

You do have to get to a working system, even if it is on a naive happy path before you can start preparing for the things that can go wrong.
