Yes it is, it’s an omnimath I’d say.
Ai will soon be able to make things autonomously, but it doesn’t know “what” to make.
Assuming there is a future where humans have jobs (otherwise this is all moot) it will be one where humans are directing ai - in this case humans would be telling the ai what to make.
In such an economy the competition will be pretty heavy for any one domain, if I am just exposed to one field there are only so many obvious ideas for “what to make” within that field, and there will be hundreds of thousands of other people competing and coming up with the same ideas and concepts.
This is why I say polymathery/exposure is valuable. You will be able to think of “what to make” in the overlapping regions between multiple fields, these special environments have much less competition so you will have more leverage.
It’s not because polymathery is somehow unique against ai, it’s because it’s still beneficial to a human regardless of if ai is also polymath.
Example: being exposed to two unrelated fields like acoustics and dentistry was necessary for someone to come up with the concept for ultra-sonic toothbrushes.
