I doubt its coming, at least not within the timescale OpenAI or Anthropic would like to believe. If we were close, then we'd see the fruits of that, which like you said, we are seeing the opposite currently.
The bottleneck was never writing code, and it still isn't. Writing code is like 15% of the job, but the labs can't tell investors "Yeah we make everyone only 15% more efficient" and still be able to raise trillions in capital. Whatever AI accelerates, the bottleneck is still code review, comprehension, and security debt.
Vibe coded slop gets abandoned because non-devs were never going to be able to use AI to make commercial software beyond an MVP. Once your app needs multi-tenant auth, session invalidation, concurrency handling, API changes, graceful degradation under load, etc. natural language prompts will fail. You still need a mental model of how things work.
When building a house, lowering the cost of bricks and getting them delivered faster does nothing to speed up the rest of the process that still relies on engineering discipline.
