Matching the OSP to the end users is the tricky part. Cadence matching is critical. It's analogous to pelotons in cycling. An ASIC is a 24-36 month cycle.
The market dynamic that works the best is consumer purchases where no financial analysis is done rather people buy tech for a purpose or for use case(s).
The next missing piece is Fi-Wi. That will make home networks phenomenal and as simple as a whole home fire alarm system. When this occurs, consumers will push back on service providers to upgrade their OSP faster because they are not being limited by the mobile phone as the primary user device. Life support use cases, redundancy and quarantining of bad acting devices will be standard practice (as are circuit breakers, AFCI an GCF in our electric panels)
Universal service is a must here too, even within a building. Life support is not only for the wealthy. (And those going to Mars won't get such either - no escaping reality)
I get the broadband focus (and that Elon Muisk is a disaster in the making,) but "Wi-Fi only inside" is not sufficient at all and there really is nothing stopping us from addressing this that I can see. Fix the homes with fronthaul and wireless to the last meters using the only two mediums that matter, fiber and RF over spacetime. Most everything else will follow.
