Linux is a full time and never ending experience, the rabbit hole you want/will dig deeper in hope to find a white rabbit !

While Linux can certainly be such an experience, it doesn't have to be at all.

If you have a defined use case for your system, and there's Linix software to support that, it often just install something like Linux Mint, install the software you need from the repos, and wahoo, you have a computer to do what you need and you just use it.

Which, for most people, is how they use their computer anyway, a few bits of software they just use to do what they need to do, no need to tinker, problems unlikely to arise.

But these people are the type that don't care, they'll use what comes with the computer they bought, and just be happy, and thus will likely never try Linux.

For those of us who like to stay in the know and on the bleeding edge, and tinkering and understanding, then it's a full time thing. But we're such a small minority.
