AI prototyping tools now produce work that looks finished rather than sketched, and that shift changes what happens in the room on both sides of the glass. A July 2025 Purdue case study found that highway traffic engineers gave only vague, preliminary feedback on rough mockups but dug in with real critiques once shown an interactive AI-built prototype — the same pattern Mozilla’s Aarjav Pandya and Nielsen Norman Group’s Megan Chan each describe independently, from a Firefox Android feature and a Ramp expense-policy editor.
The two hosts trace the mechanism through all three accounts, then test it against the strongest objection: survey data showing most designers still don’t trust AI output for production, which suggests the real problem was never appearance but a lost cue for telling stakeholders something is still cheap to throw away.
