People have been specializing for years. Some 30 years ago, I worked on a 3-D display at a college. One of the kids who programmed it up was very good—his code almost always worked the first time. But, he had never used a soldering iron.
There’s a big difference between “soldering iron” and “screwdriver”.
I use one on a near-daily basis; the other I hardly ever use (but I do have one).
But, he had never used a soldering iron.

There is a whale of a difference between a soldiering iron and a screwdriver. I can’t solder but I can screw anything.

Bet he didn’t know the difference between acid and rosin core solder, or lead free solder.
I’ve been an engineer for 25 years, and we’re not allowed to solder any longer. Techs do it. Besides, they do it daily and are far better at it.
That and there are stricter lead safety rules in place that have come in the past 10 years or so. Engineers don’t want to keep up the safety training.
