What is stopping Anthropic, Google etc from essentially building models that completely replace the concept of code?

You point a model to an API and get a fully working UI right away. I don’t mean an agent CODED the UI - I mean the model inferred it from its training data and renders it to you “live”

Or the other way around? You serve it a UI- and it acts as the backend etc? State and persistence becomes an issue, but the model could freeze things into deterministic structures (specific parts become -just in time-frozen, for example when data needs to be saved)

Maybe this is old news already- but the consequences are kind of mind blowing
