> Fiber is a waste of money at this point. I just got gigabit and it has essentially no marginal value compared to my only 75mbit connection. Most consumer hardware can't really do jack shit with it.
1) The benefit is to businesses first, not necessarily consumers. Solid telepresence would allow specialists in various fields (medicine, engineering, etc.) to be located away from the big cities. It would also allow businesses to locate away from the big cities.
2) Part of the reason we don't have new applications is that so few people have gigabit (especially upload). Why write an application that requires gigabit when nobody will use it?
Every order of magnitude jump in communication upload speed spawned something new in technology usage that we couldn't see at the time.
300 baud -> email, BBS
9.6K baud -> graphical Internet
128K baud -> napster, MP3
1.0M baud -> video
So, what is waiting at 10M (we're just getting here in the rural areas and it's patchy), 100M, or 1G upload?
