You answered your own question. I don't want my great-grand-children to be the first to have a great Linux Desktop. Ideally, I would like to have it now. Unfortunately, as things go in capitalism, the easiest way to accelerate development of something is with money.
Where's the incentive in any of that? Pour money in linux desktop development for what? (So we can have linux desktop... sooner?)
If there were any money to be made in linux desktop, it would have already happened imo, or otherwise the cost-opportunity is still to high.
If anything, more than a gold mine, looks like a gold sink to me
And don't get me wrong, been on arch for 7 years and i've long since ditched win. But I still don't think there's any meaningful incentives for companies to push for linux desktop.
If the linux desktop space is advancing so slowly is precisely and because of the opposite: because desktop linux is made and maintained by a bunch of people who do it for free.
Alas, valve has done a pretty good job with proton and steamdeck which is helping the ecosystem. here's to hoping wayland and nvidia drivers 555 with explicit sync[1] we might get something decent next few months.
