> Part of the issue is that people who are experts at creating ML models aren’t experts at all the downstream tasks those models are asked to do.

Yep. CAD, music, poetry, comedy. Same pattern in each.

But it's more than not being experts: it's about a subliminal belief that there either isn't much to be expert in or a denial of the value of that expertise, like if what they do can be replicated by a neural network trained on the description, is it even expertise?

Unavoidably, all of this stuff is about allowing people to do, with software, tasks they would otherwise need experts for.
