It's incredibly hard to maintain your own voice while using LLMs. It requires deep discussion with the LLM itself so that it comes to understand your perspectives and also explains to you the premises on which its own recommendations are based.

I haven't really done a systematic analysis to compare the quality of fully human-written content and content generated via this kind of deep human-AI collaboration, but my intuition is that the latter is vastly superior. Perhaps AI at its best is a research tool, but a genuinely intelligent one that we need to engage in conversation with in order to use to its full potential.

The sense that I get is that as a conversation gets more in depth, the LLMs start behaving more like reasoning engines and less like statistical averaging machines. The former is vastly more useful to a person who wants to develop an idea and articulate it well.
