Define normal. I would argue at least 75% of the US population has zero interest in learning how to install a new OS, let alone actually do so themselves.

I say this as a decades-long Linux user (who has tried to evangelize it many times).

Gamers are one of the few demographics still buying new Windows PCs. There are now so many discord servers and subreddits filled with people discussing which Linux distro to use.

Honestly for your average home consumer, there isn't much need for a Windows PC now days.

I can't drive stick.

This doesn't mean if someone gave me a manual car I wouldn't try to learn.

If your around a bunch of car people then it's much easier to over estimate how many people will want to drive stick.

I would argue its close to 99% of the population. Technical people like us usually live in a bubble.

> has zero interest in learning

Well I can agree with that, but that's not the same thing as being incapable of doing it. Both of my parents could easily install Linux, it's infantilizing to argue that they can't fill out a user wizard and select a drive to wipe.
