Showing stakeholders prototypes is often a high-wire act. Back in the old days, that’s why we showed wireframes prior to high-fidelity comps, or mockups. But now with tools like Lovable or even Claude Design, where the prototype demos really well, it’s easy to mistake it for a product that is shippable. The stakeholder in the room could easily say “ship it.”

That used to be where the Figma-to-code handoff became visible. Now it’s invisible. Greg Kozakiewicz, writing on LinkedIn, wants designers to see it again. He updates an old construction-industry line for the AI era:

We used to confuse the drawing with the building. Now we confuse the prototype with the product. A working prototype also accepts everything. It will let you register, log in, fill out a form, submit something. It all works. In the demo. On a good laptop. With a fast connection. With someone who knows what they’re doing and what the app is supposed to do.

The design-to-code gap didn’t vanish when AI made prototypes interactive. It went underground. Now it shows up as a stakeholder saying “looks great, let’s ship it” to something that couldn’t survive real data or production constraints. Kozakiewicz puts a number on it:

AI gets you to about 60%. A solid, reasonable, generic 60%. The layout makes sense. The flow is logical. The copy is clear enough. It looks like a product that works. And for a lot of people, especially people making decisions about budgets and timelines, 60% looks like 90%. Because the last time they saw a prototype, it was a static Figma file with “Lorem ipsum” everywhere.
