The city demo was really unconvincing, heh. Super laggy for the amount of detail. I click "wow mode" and the whole thing disappeared. idk. feels like non-coders getting excited that they think they're getting 80% of the code when in reality the other 20% is 80% of the work and going to be exponentially harder to squeeze from the AI.
I do think the vibecoding tools are good at spitting out well-defined CRUD apps, but more creative things are still rough without experienced hands to guide things along.
