I'll be surprised if it's still around (as in not killed by Google) in a few years. Besides, I don't see it ever becoming popular enough to be an alternative to Linux outside of Google.
Why? It was just officially rolled out to its first devices less than two weeks ago. It isn’t like a google service that can fail/not get enough traction fuchsia already has a bunch of users (anybody with a google or android device) that it could be rolled out to. I imagine it will not replace android in the next five years but simpler devices it’s almost guaranteed to be the main OS shipped going forward.
