Honestly, no - vibe coded projects that aren't done well never launch. So if you ever reach a "Day 1", you did well enough that you can probably roll with it for a couple years before you need a rescue. And if your business survives those couple years, it means you've hit the market correctly, which should then be able to fund a project to re-architect for sustainability. Also, vibe coded apps are almost by definition something that an AI can iterate on because it came from an LLM in the first place. Legacy apps tend to exclude LLM-based assistance because the models' training is insufficient on obscure ancient tech stacks.
