Both had a working prototype. The flaw everyone is making is that they are over focusing on the artifact and not that they have a shared tangible object that they can both editorialize and iterate on.

These systems should allow rapid iteration on discovery and thinking. One can now make a prototype a day that would have taken a week. That means that we should be able to converge on a much better design in the same amount of time it would have taken to make a v0 that turns how to have systemic flaws.

AI should scale our understanding of systems, not just shovel out half baked features and apps.
