To make my argument clearer, I will use you as an example; please forgive me.
If you have a comparative advantage in maths, and decide to change your comparative advantage to medical, computer, or social science, as soon as you have caught up on the fundamentals of the field necessary to make an informed opinion you will already have a comparative advantage because of your background.
Your proficiency in maths lent you a comparative advantage in maths; your comparative advantage in maths lends you a comparative advantage in [economics]; your comparative advantage in maths and [economics] lends you a comparative advantage in [biochemistry], etcetera.
I think this makes sense. We need to distinguish between something like “obvious current comparative advantage” and “less obvious potential comparative advantage.” In practice, the heuristic “stick to your comparative advantage” may optimize excessively for the former at the expense of the latter.
