>I’m hiring them to do the one thing they say they can do.

If you hire an amazing programmer but then ask for a quick report on their implementation and it's gibberish. Is that satisfactory? Their job isn't to write reports.

If you ask them during lunch to grab your meal from the desk and they spill it everywhere, is that satisfactory? You didn't hire then for their ability to carry a plate.

EDIT: I should add here that I agree with your hiring approach. I just think you're critiquing this quote in the wrong way. The point of the quote is that humans have a capacity to learn and perform many tasks, even if they do some better than others. LLMs hinder this ability.
