Also bear in mind that a lot of folks want to be seen as being on the bleeding edge, including famous people. They get money from people booking them for courses and consulting, buying their books, products and stuff. A "personal brand" can have a lot of value. They can't be seen as obsolete. They're likely to talk about what could or will be, more than about what currently is. Money isn't always the motive for sure, people also want to be considered useful, they want to genuinely play around and try and see where things are going.
All that said, I think your approach is fine. If you don't inspect what the agent is doing, you're down to faith. Is it the fastest way to get _something_ working? Probably not. Is it the best way to build an understanding of the capabilities and pit falls? I'd say so.
This stuff is relatively new, I don't think anyone has truly figured out how to best approach LLM assisted development yet. A lot of folks are on it, usually not exactly following the scientific method. We'll get evidence eventually.
