There is an argument to be made that gigabit ethernet is "good enough" for Joe Average. Gigabit ethernet is ~100MB/s transfer speed over copper wire or ~30MB/s over wireless accounting for overhead and degradation. That is more than fast enough for most people. 10gbit is seemingly made from unicorn blood and 2.5gbit is seeing limited adoption because there simply isn't demand for them outside of enterprise who have lots of unicorn blood in their banks.
