Moreso came out of pivot into role specialization in IT. I remember coming out of college in the early 2000s, roles were much more bucketized -- Help Desk, Systems Administrator, Network Administrator and Programmer is pretty much all we had at Sony where I took my first job. Many, many more jack of all trades, master of none types.
Then C-Suites and MBAs put on their dunc... thinking caps and ushered in specialization all over the place. Within a few years, that programmer role now was split into individual languages or technologies and we suddenly had 5x the people. Same with systems administrators, getting a mail admin, Windows admin, Linux admin, so on and so forth.
When I'm at now, we have people that know a singular language or technology and are completely fucking worthless outside of it. I'm talking lacking fundamental cursory computing knowledge to boot.
That said, all IT professionals all dead inside to some degree.
