My wife switched from Windows 10 to Gnome 3 without too much fuss when her computer died witohut warning. She needed a laptop that day, the only one I had available was my spare thinkpad I just created an account, a new luks passphrase and she just started using it. Sure at first she had to learn a few things but nothing that lead to swears. My daughters have been using gnome 3 since they were of age of using a computer and like it much more than the windows at their mother's place.

Grumpy luddites gonna be grumpy luddites but I am pretty sure that Gnome is more approcheable than windows and macOs for the newer generations who are more accustomed to mobile interfaces since they are kids.
