You don't need faith, you just need to look around: It's already shining!
Support for Linux in consumer software applications and devices has improved a huge amount over just the past few years. Using a Linux desktop in 2024 is not a second class experience at all anymore.
Sure the userbase is still quite small relative to Windows and MacOS, but in absolute numbers it's still a huge population of users, and it's also growing very fast. That combined with the fact that supporting Linux is typically quite easy means that more and more vendors are supporting it, which is creating a positive feedback loop by enticing more users.
No need for pessimism here.
