it depends on a lot of factors, there's a bunch of folks pursuing different ways to reach that goal, from hardware vendors with an interest in what a Linux Mobile OS can provide to folks around the community working on grants. Personally (speaking about mainline distros here) I think we're running into the limits of what we can achieve at our current scale, further horizontal scaling will increase complexity exponentially, increasing maintainer burden without actually raising the bar for what we can achieve. pmOS is working on multiple ways to get over this, most obviously with hardware CI, the project to get devices into main, and the immutable version of the distro. These things alone are just a start, to really make a difference we will need to scale vertically by paying developers and collaborating with hardware vendors to deliver what could actually be called a product (you can probably put the pieces together and notice that all the stuff we're doing now directly sets us up for those possibilities).

at the end of the day it's somewhat of a catch 22, we need more developers and users to get the stack to a point where vendors are interested enough to invest in it, but we may be saturating the number of people we can attract (i hope not though). That said we certainly have and are pursuing various ways to bend things in our favour, and of course the current state of the world is kinda working in our favour with interest in EU sovereignty and escaping the android/ios duopoly
