I don’t think wireless is the future due to limited spectrum and high latency. The future is still wired, it’s just that private companies can’t be the entities trusted to do the build-out — it has to be a public utilities project.
China did a great job at building out a fiber network. Unfortunately it's compromised by the GFW and other issues. Australia recently attempted to fund a national plan for fiber deployment, but managed to privatise the implementation to the point where it was never delivered and has become a joke. A couple of years ago, you still literally couldn't get a connection right in the middle of Sydney. https://en.wikipedia.org/wiki/National_Broadband_Network
Their take: There is no significant demand for wired connections above 25 Mbit/s and consideration of upgrading the network will not be undertaken until demand for high-bandwidth services is proven.
Not too long ago 10 mbits was ‘broadband’, so, maybe various forms of wireless will be just fine. Certainly more flexible in terms of long term options
