I still don't understand why desktop OSes now have mobile style taskbar icons that are twice as large as they need to be, grouped together so you need to hover to see which instance of what is what, and then click again to switch to the one you actually want if you can even figure out what it even is with just a thumbnail without any labels. All terminal windows look the fucking same!
Win NT-Vista style, aka the way web browsers show tabs with an icon + label is peak desktop UX for context switching and nobody can convince me otherwise. GNOME can't even render taskbars that way.
Most people coming into the workforce today have grown up on iOS and Android. To them, the phone is the default, the computer used to be what grownups use to do work. Watching them start using computers is very similar to those videos from the 80s and 90s of office workers using a computer for the first time.
The appification of UI is a necessary evil if you want people in their mid twenties or lower to use your OS. The world is moving to mobile-first, and UI is following suit, even in places it doesn't make sense.
Give a kid a UI from the 90s, styled after industrial control panels, and they'll be as confused as you are with touch screen designs. Back in the day, stereos used to provide radio buttons and sliders for tuning, but those devices aren't used anymore. I don't remember the last device I've used that had a physical toggle button, for instance.
UI is moving away from replicating the stereos from the 80s to replicating the electronics young people are actually using. That includes adding mobile paradigms in places that don't necessarily make sense, just like weird stereo controls were all over computers for no good reason.
If you prefer the traditional UX, you can set things up the way you want. Classic Shell will get you your NT-Vista task bar. Gnome Shell has a whole bunch of task bar options. The old approach may no longer be the default one, but it's still an option for those that want it.
