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.
"Vibe Coding" seems like magic at first but starts falling apart realllll quick at a certain complexity level or if you want to make changes to existing code. If you don't keep an eye on your architecture, you will end up with a bowl of untangleable spaghetti code and some comically terrible engineering choices. That said, agentic coding in the right hands with well defined tasks can have you outputting days / weeks of work in one session; it's not every task, it's not every session, but if you can drive the "idiot savant" in the right direction it's truly an awe-striking and almost alien process to behold.
I've just recently set off time to have a few extended coding sessions, and the results are all over the place.
Guided in a good way for well defined tasks, it has saved me days if not weeks. Given more vague, or perhaps unreasonable tasks, it will quickly devolve into just delivering something, anything, no matter how "obviously" wrong it is.
