Writing (unassisted) is probably the first step towards your own independent thoughts. I'm reminded of that scene in "Ghost in the Shell" where some guy ask the Major why he is on the team (full of cyborgs) and she responds something along the line of "Because you are basically un-enhanced (maybe without a ghost?) and are likely to respond differently then the rest of us; Overspecialization is death." I think a diver…
The scene you mentioned (amazing movie and holds up to this day) with the Major and Togusa:

While I frequently use a similar argument, "We need someone 'untainted' to provide a different point of view", my honest opinion is somewhat more nuanced. These models tend to gravitate towards some sort of level of writing competence based on how good we are at filtering pre-training data and creating supervised data for fine-tuning. However, that level is still far below where my current professional writing is and I find it dreadful to read compared to good writing. Plenty of my students can not "see" this, as they are still below the level of current LLMs and I caution them to overly rely on LLMs for writing as they can then never learn good writing and "reach above" LLM-level writing. Instead, they must read widely, reflect, and also I always provide written feedback on their writing (rather than making edits myself) so that they must incorporate it manually into their own and when doing so they consider why I disagree with the current writing and hopefully learn to become better writers.
