I don't understand the point you're making here. You initially said that Linux being arduous is an outdated trope and then admitted that the only people you see using Linux are software engineers and that non-technical users can't even comprehend the install. Who is Linux non-arduous for, then, except technical users and software engineers? Was your argument meant to apply to only the technical users because that wasn't clear, if that's the case.

Yes

Any install, you don't see them installing windows either. I'm not sure my mother (for instance) really comprehends what an operating system is as a separate entity to "the computer".

My argument, as stated, was that it works fine and the trope that you'll spend your life fiddling with it is outdated. This has absolutely f*ck all to do with how many people use it, as that number is affected by a lot of other factors.
You'll find elsewhere on this page I've talked about messing around with xrandr to get DPI-related stuff looking good on Xfce. And yes, I had to spend some time figuring that out, an evening of my life gone.
I had to spend a comparable amount of time recently trying to figure out how to get my bluetooth keyboard working properly when attached to OS X, and ended up creating a custom keymap for it. And since Catalina my macbook pro has spontaneously rebooted a bunch of times while asleep.
Windows has been a complete bastard with its update packages lately, and it took days of effort to update the four PCs in our house to Windows 10 1903, for no known reason, having got stuck on an older version that was going out of support and started throwing up warnings about being out of date. I'm still not sure how I fixed that, having tried a whole bunch of different methods over the course of several days. Incidentally the old version it got stuck on only had partial support for HDR which explains a load of other weirdness I was seeing on one of the machines.
So to me this idea that Linux on the desktop is a pain in the arse to keep running properly but other systems are not just doesn't ring true.
They've all cost me time and effort lately. Probably the least troublesome system we have in the house is a laptop running Linux Mint that we use to order pizza in the living room... Or my old ARM chromebook I suppose, but that's in well deserved retirement now.
