More techy people migrating to linux would be good, but that won't change the fact that most people don't even know that they can change their os, let alone how to do it.

More techy people joining would mean that we would hopefully get more fixes to issues linux has, as there would be more people bringing attention to them and maybe there would also be more people willing to help fix them.

When those issues are fixed, we might get to step two. Honestly not even sure what that step would be, but maybe it could be that more it-departments switch over to linux, which would get more people familiar with it, which would hopefully make manufacturers more likely to ship computers with linux.

All that is going to take a hell of a lot of time. And honestly seems unlikely to happen in the next 10, heck even 20 years. People are already so used to Microsofts shenanigans that they would have to fuck up majorly to get enough people to switch that it would matter. People are lazy, for good and bad, and as long as Windows at least mostly works fine, they'll just be stuck using it.
