Strict universal nomadism is incompatible with agricultural development. Most of human existence has been nomadic, but the recent default for ~10000 years has been sedentary (non-migratory) mainly because of agriculture. And we've replicated the "farmer schedule" in most all subsequent careers.
The rise of interdisciplinary personalities (or at least recognizing this is a thing) might just be a new old thing: the modern version of a nomad who had to become near expert at a wide variety of things for survival as well as intellectual stimulation.
It's not nomadic in the sense that nobody was moving thousands of miles in one fell swoop into completely foreign environments full of complete strangers and an unfamiliar culture.
Nomadism is entirely compatible with agriculture, actually. A lot of Native American tribes had a nomadic lifestyle while simultaneously relying heavily on intentional agriculture for a lot of their caloric intake.
"Strict universal" is doing a lot of work there. I suspect very few societies would end up even qualifying as nomadic with that.
