This isn’t universally true and depends heavily on what the user uses their PC for and what hardware they have, but I have family members who would constantly ask for tech support for Windows. Just neverending issues. I installed Ubuntu for them, and tech support requests dropped by an order of magnitude.

Nowadays they barely even turn it on, it’s all phones and tablets.

Aww, I’m not on the list. Is this a personal failing of mine? Am I just too agreeable?

As someone physically capable of playing games with the blinky shiny lights, they aren’t all they’re cracked up to be. My top two games atm are Manor Lords and MENACE, both of which should be perfectly accessible to you.
