Home users have only incidentally arrived at GigE because the economics of GigE over Fast Ethernet made it compelling to provide it before there was widespread need. Most home "modems" for DSL or cable are at best 100Mb/s, many are still at 10Mb/s. Also home users are substantially more likely to use wireless connections, which is significantly bandwidth constrained even compared to GigE let alone 10GigE. I don't at all see the use case beyond niche.
South Korea is the world leader in internet bandwidth provided to the most people. Most of this has to do with government policies. Even there, they are nowhere near 1000Gb/s speed. Experiments have started with GigE speeds, but the average is 17Mb/s with a peak of almost 50Mb/s. [1]
Yes there's desire but I just don't see the money there to broadly role out internet connections inside of the next 10 years that will utilize 10GigE connections. We'd need a significant leap in performance for essentially no cost increase to get there.
