> LLMs have also given engineers access to clear communication.
A lot of the time, the inability to express an idea clearly hints at some problem with the underlying idea, or in one's conceptualisation of that idea. Writing is a fantastic way to grapple with those issues, and iron out better and clearer iterations of ideas (or one's understanding thereof).
An LLM, on the other hand, will happily spit out a coherent piece of writing defending any nonsense idea you throw at it. Nothing is learnt, nothing is gained from such "writing" (for either the author or the audience).
Recently read a tweet suggesting to ask an llm to defend a position you know to be false. It's quite eye opening. I mean, it shouldn't be, if you did debate club etc. Or know how lawyers and politicians work. But it's quite revealing how it can piece together a good defense, selectively quoting real facts, embuing them with undue weight etc to make the thesis stand quite well.
