In 5-10 years maybe. Now virtually all sites are slower than a ~ 10-50 mbs connection so having all that extra bandwidth doesn't help you at all. That's the reality.
For what % of people? We should assume that bigger pipes cost more money, at least they do now, so why should Jack and Jill pay for 1Gig/s when a 5-10-20 mbps is more they need? Cable seems to have no problem bringing movies through the old copper wires.
This is true! However costs over the years have plummeted for those uplinks and the reduction in costs have not been passed on to the consumer through much lower priced service.
