I've been "doing this" for over 30 years now and I consider these LLM results to be fantastic.
If one has a deep, conceptual understanding of tools, systems and protocols and if one has the ability to carefully provide careful, concise specifications, these LLM tools are like being granted superpowers.
In fact ...
My next project upon which to bring LLM tools to bear is a fully local, solar-powered, self-hosted LLM toolchain.
Not only do I intend to never work without these tools again, I intend to do so without the ongoing environmental externalities that they produce.
