Little anectode …
My Parents are over 60 and know a how to use a computer on a basic lvl… like installing software etc….
6 years ago I forced them to switch to linux with linux mint and christmas presents….
It was a hell of a work at first. To show them how it works etc …
They adapted very fine and are now big linux fans, because its so easy and not overloaded with shit you dont need.
Every other person in that agegroup that is using windows has a shitload of strange software because it was the anwser to some problem on google and at leas 10 accounta for things they dont understand….
My parents are super happy with linux.
My mother even shoked me when she had a problem with a printer and was suddenly using the comand lines for showing me that the printer doesnt react… that was a crazy moment for me … mama using shell commands …
I think if mama is using comand lines linux desktop is mainstream!!!
Btw she was also surprised by the amount of help she got in the comunity
