Hey, with any luck, running one of these bots with the capability to replace me will cost just as much as hiring me.

Against the cost of living in the US, workers in the US are about as cheap as they come, second to maybe sweatshop workers in free trade zones or slaves in Dubai.
ChatGPT costs the same, regardless of the difficulty of the task, which is not the case for humans.
Given how badly the humans performed, I suspect a lot of them are either not bothering to read the prompt or using a worse bot than ChatGPT. Not surprsing they are so cheap.
If you tried to pay people to do it properly then presumably it would cost much more.
