I am always worried non-programmers don't sufficiently understand how pathetic it is that we limp along with bloated Unix and other accidents of history that were never retired. And this lassies-fair approach to cleanliness and reducing complexity both makes us more vulnerable and less productive.
Why single out Unix and not, you know, Windows ?
I use Unix every day but rarely Windows so I sometimes don't remember it. Our industry self-congradulates on not using Windows like those untechnical normie companies or whatever, but then forgets that other than being FOSS (most of the time), Unix has all the same problems just to a lesser degree.
Maybe this is the transition plan we need; first ban Windows in prod for things important enough that government is going to take on the costs if something goes wrong.
Then, at some later point, ban Unix too for all the same reasons, just less magnitude.
