If I want something done, I'll seek out someone with a skill set that matches the problem.
I don't want AI to be as good as an average person. I want AI to be better than the person I would go to for help. A person can talk with me, understand where I've misunderstood my own problem, can point out faulty assumptions, and may even tell me that the problem isn't even a problem that needs solving. A person can suggest a variety of options and let me decide what trade-offs I want to make.
If I don't trust the AI to do that, then I'm not sure why I'd use it for anything other than things that don't need to be done at all, unless I can justify the chance that maybe it'll be done right, and I can afford the time lost getting it done right without the AI afterwards.
