For someone as tech illiterate as my mom, I’d advise against trying it.
But you are here and my mom would never know that Lemmy is a thing. You also ask about Linux.
I’d guess that you will have great fun using and appreciating what Linux and the foss communities have created.
That was really nice but I think the lady was lucky that she met you. Can you imagine if she had met Linux Torvalds himself? He would have told her off for not knowing that the 2.6 kernel was many years old, the whole Linux world had moved on with strides beyond this old piece of software and reached 6.5 and there was no reason wasting everyone’s time with this kind of question. Plus: “we never, ever break the user experience and hence the mouse should work without questions!”
I have been using wayland on kde the last two years on Debian and MX Linux with zero issues. My general usa includes coding, music production, Libre office and web browsing. So, no much gaming, if that is your concern.
