Android is a repudiation of traditional “distro” Linux userspace. I think it’s Android approach that has the best chance of reaching mainstream adoption in the laptop form factor with consumers.
I'm not saying "android on a laptop is the way of the future". I'm saying the Android model, to sweep aside the status quo distros and start fresh with new approach to userspace, is the path I see most likely to bring Linux to the masses in laptop/desktop form factor.
If the people you see using Linux on the laptop are developers, then I don't think they count as "consumers" - they're on the production side of things! I don't know any consumers who use Linux on a laptop. I last gave it a shot in 2018 but decided it's not for me.
Consumers will eventually follow. (see android).
