It's seems to me that it would require a pretty radical change for fixed wireless to progress a whole lot beyond what it's currently capable of. Maybe 6ghz being opened up will allow for using much wider channels, and keep things interesting, but I don't see things like MU-MIMO being more than an incremental improvement, like practically everything over the past decade or so.
60ghz has the potential to be a true competitor to fiber, but that's going to require a completely different network design than what we're used to.
