Many people don't understand this, even big tech engineers. They see LLMs as a bottleneck. It's more that they don't understand how to use it to multiply their skills, just basics and code gen.

I use multiple Claudes at a time, daily. It's precisely because of that experience that I wrote:

  LLM + framework you don't understand goes in ... unmaintainable garbage comes out.

If you just have it built something with a framework you don't understand, it will do so just fine! But over time every "vibe coded" change you make will drift it further and further, until you are left with a mess of vibe-coded spaghetti.
