The challenge I've had is I tell it to do {thing}, it does {otherThing} after getting distracted. Then I get annoyed (let's not mention how I probably half-assed the instructions and wouldn't expect a senior human to be able to succeed).
For me, it was a CI/CD issue with our two person startup. I bypass CI/CD often because it was built to catch the AIs. Damn thing went chasing rabbits. Later that day I talk to my cofounder, who says: I have to go chase down this very important CI/CD issue!
Turns out both humans and AIs get distracted relatively easily.
I find that if I think of my AIs less like (deterministic) software and more like leading actually employees that I both get better output and curse (a lot) less.
LLMs _were_ trained on human writing, so it makes sense to me that they tend to act human-like... for better and worse. So yeah, they do dumb stuff, and so do people.
