Adoption rate is increasing from what I’ve heard. But you’re right, Linux/a Linux distribution isn’t going to take over anytime soon.

But I think once those users truly switched to Linux, very few will switch back. Sure there’ll be the odd gamer who absolutely “needs” to play that one game which has anti-cheat that’s unsupported on Linux. But other than that, once you’re in, you’re likely in for good. And long-term you pass it on to your family, mainly your children (my first computer was a DOS/Windows machine mostly because my dad used the OS himself then).
