That may not be the right question. There are all kinds of things that theoretically we could replace with bots over humans but we do not because of convention. For example Home Depot or any Home/Shed tool supply store. Let me explain?
In Neal Stephenson's The Diamond Age there is a class of humans who generate handcrafted items. They have machines that produce anything to molecular perfection and yet humans (due to our nature) seek to distinguish themselves from other groups of humans using objects. In this case flawed objects, but objects they willingly paid for nonetheless. It's all about status!
This is not outlandish to me. I want to construct a Tiny House. I know that when I develop the skills and accomplish this task I will place considerable value on my creation.
It is extremely likely that this is not optimal because of the division of labour. However I will enjoy my Tiny House regardless.
AI can endlessly optimize production but it cannot manufacture personal pride or social class.
Human nature creates scarcity naturally even within a state of abundance.
We really do like to belong to tribes and be 'self made'.
Before the industrial revolution we had lots of horses for horse power. Then we made engines which replaced horses. Horses didn't change jobs, they couldn't.
Low hanging fruit here is education, tradespeople (AI will not be repairing your car for a while), managerial and oversight tasks, QA engineers, blah, blah, blah. There are plenty of things that humans will be doing better than AI, and from those we'll probably continue specializing and be more ready to handle when automation of more complex tasks does eventually happen.
