Far too broad a brush stroke there, but yes, there are some specialists who go way too far. A great quotation from “Ghost in the Shell” (the anime movie, not motion picture), which gets it right, IMHO: “overspecialize, and you breed in weakness.” It isn’t specialization which is inherently bad, but rather over-specialization which asks for big trouble.
Theravada forest monastic culture in the West is fantastic for rounding out the newly-ordained in many generalist life skills. This includes (but is not limited to) things like wood chopping, heating a kuti with a wood-burning stove, starting/maintaining electric generators, the use of every carpentry-related power tool in the known universe (pretty much) etc. One also needs to make friends with (cultivating Metta) to all sorts of creatures one shares the forest with: bears, wolves, coyotes, bobcats, bulls, etc. I’m not kidding here.
The lifestyle is simplified greatly from “normal” Western living (if there is such a thing anymore). It’s very grounding.
Whatever specialist one used to be before ordaining will very necessarily need be put on the shelf. One will probably not survive in the robes, unless one is willing to become the all-around generalist one never knew one was sorely lacking knowledge about being. It all serves an important purpose: anatta will never really be seen to any depth, without this setting aside of one’s old identity.
Given enough years of practice - setting that old identity aside well enough that one can revisit it without it sticking - then one can draw upon those skills one used to have (setting them down just as soon as they aren’t needed) and one now owns the skills, rather than the skills owning one. This is spiritual integration.
Remember when the Buddha said he thinks when he wants to, and doesn’t think when he doesn’t want to? Well, that’s what one’s former specialization ends up looking like after enough practice. Something one doesn’t think, when one doesn’t want to.
