What to do with the executive prototype

What do you do when an executive brings you a prototype they vibe-coded that they are super-excited about?

“Let’s talk about your aims behind this, what it’s meant to accomplish, how it does that”

Note that is not just the appropriate response to an executive; it’s the appropriate response to ANYONE’s mock/prototype/sketch. We’re going to need to get really good at this response since roles are blurring and tools are helping folks make stuff they might not have bothered with before. And we’re going to need to get really especially good at offering alternatives to simplify, to make more conformant with customer mental models, to detect and form a plan to learn things we need to learn, etc.
