I don't buy applying comparative advantage in this case, even after reading the more extended article that was linked to. The argument makes the fundamental assumption that the marginal value of one unit of a specific type of work is fixed. Whatever is the most profitable use case for AGI is the one that all the compute and power will be plowed into. But what kind of economic activity actually has a fixed marginal utility, no matter how much of that activity there is? I think it's like, none at all? No matter what you're doing, there's eventually going to be diminishing returns as you do more of it. As the highest value use cases are saturated by AGI, the opportunity cost of doing something else diminishes. And comparative advantage only works because of the opportunity cost.
