Terabyte Bandwidth to every home?

A justification of available bandwidth in the setting (if one is needed)

Bandwidth will almost certainly be a standard utility by 2100, like electricity, where you pay by usage. It is in the network companies interest to let you use as much as you want, even for peak loads, otherwise they potentially lose out on revenue. Given that the installation cost of a network cable vastly outweighs the cost of the cable, there seems little reason not to install a standard 1 Terabyte optical cable to every location. Electricity supply follows a similar model today - I have a 100 amp electricity supply, but use less than 3% of that on average - and probably less than 1% when the house was built 30 years ago.

I would expect bandwidth increase to follow Moores law for some time to come yet. It has been following a similar progression for as long as I can remember (back into the late 70's). Even if the bandwidth curve flattens out in the 2020s (along with complexity) that still implies a 4000 fold increase in bandwidth (12 doublings) and probably lots more.

Taking the 1 TB* per building as equivalent to 0.5 mbps* 'broadband' today that only implies 24 doublings - and Moores law implies doubling every 1.5 to 2 years. It seems quite conservative over 100 years. So if I get 4 mbps now, I will get 1TB on a 50:1 contention ratio or a guaranteed 20 GBs in 2100. So a couple of active slinky feeds and you are using 1% of the available bandwidth. Not dissimilar to the current electricity model. That also means you could download a 100GB infomorph in 5 seconds at worst, or a Ghost in less than 85 minutes, usually less than ten minutes.
