What do you find confusing about the document encouraging use of LLMs?

The document includes statements like "LLMs are superlative at reading comprehension", "LLMs can be excellent editors", "LLMs are amazingly good at writing code".

The caveats are really useful: if you've anchored your expectations on "these tools are amazing", the caveats bring you closer to what they've observed.

Or, if you're anchored on "the tools aren't to be used", the caveats give credibility to the document's suggestions of the LLMs are useful for.
