Right again nnnBrewery.
For now Fibre is the king. It will not be obsolete anytime soon. It is the backbone of the networks, and will probably always be. Wireless is complementary. For the user/customer it is the convenience of wireless that will be enough for most people. It's the plans and tower congestion that can suck right now. But still many people choose mobiles or mobile broadband. What about in 10 years? 20?
Article from 2015. 1 Terabit achieved.

Even with 5G towers they will need fibre to connect between them.
My sister and her 2 children family use Optus 4G Mobile BB between the 2 places they reside due to work. 1 plan 100GB $70 a month with unmetered Netflix (The kids use 150GB unmetered a month just on Netflix). At one location they can't get fixed or or even Fixed wireless NBN (they tried very hard) but always have a 4G signal.
One little pebble 4G modem, High speed broadband everywhere from their car, to the yard, travelling, at a friends house, in a car park.
They have unplugged and will not go back to a fixed line. 4G has many limitations but it's real, now. NBN would not help them even after several property visits.
When the Wright Brothers flew their first successful plane the horse and cart was king, roads were no longer limiting but still necessary for slower, bulkier things.
Who knows where tech like Quantum Entanglement routers and Qubit Networks (as a rabid example) will take us in the upcoming years.
Anyway now I'm drunk and off topic.
NBN good, Alcohol Bad.
