There's absolutely no reason that we shouldn't have the capability (in the near future) to generate entire websites with a click of a button and narrated instructions. This is definitely the step in the right direction. Congrats on the progress!
For declarative languages, this could be good. This is the “centaur” period (human + computer was better vs just a human or just a computer) that Garry Kasparov touted, before the computer-only part became better. (Chess was much easier to do play against itself adversarially though, harder to simulate how humans would react to your website so you can’t train it MCTS style).
BUT...
For imperative languages with side effects, we have a long way to go. We would need a completely DIFFERENT model of AI, perhaps closer to Cyc than GPT
