Let's say that happens. What reason is there for the company to employ the meat proxy? The company can just run the LLM in a loop and lay off the employee. There's no point at which this methodology will work for the employee

I would argue that there's still an important role for human employees as compliance ablative armor.

The human's purpose is to keep an eye on the LLM, occasionally intervene/interfere with its work, and most importantly, incur social/legal liability for anything that the LLM does wrong.

Kind of like the backup drivers used by self-driving cars.
