I use LLMs daily to piece together technical reports and smooth out rough drafts. It saves me hours of time / week.
I also use it to augment my technical work, because I don't want to be out of a job one day with no marketable skills, except driving an agent harness.
There is a percentage of the population that thinks LLMs are actually intelligent and truly can't tell the difference.
I think others just want to live life as a passenger, not think, and have AI do all the work.
