I was already somewhat interested in Linux (as a long time Windows user) when I started studying Computer Science, mainly for it’s core philosophy of freedom and openness.
Given that most courses used Linux as the default OS I installed Ubuntu on my laptop to dual boot it with Windows, and began getting familiar with it.
Over the years I started using Linux more and more, making it my main OS, with Windows still installed for the few programs I couldn’t use otherwise. Over time this set of programs became smaller and smaller, until it was just games.
Last year I bought and assembled a new PC to replace my laptop for daily uses, and given the higher specs and better support (AMD GPU instead of Nvidia) I see no reason to have Windows on it at all. Everything I need runs perfectly fine there.
I use Arch, btw.
It’s also possible we’ll see something like a EU law forcing PC manufacturers to offer a choice for the pre-installed OS on devices they sell.
