Fibre is all well and good, but the last mile into everyones home is still going to have to be a cable connection for higher-than-dsl speed
My Verizon FIOS service begs to differ. So do the lucky folks with Google Fiber. In fact, when I used to have DSL my 10+ meg connection was on par with the local cable provider's speeds -- without the terrible latency at peak times that my cable-subscribed neighbors experienced.
Your statements might be colored by a poor experience with DSL. Some installations are better than others -- it seems to be a neighborhood-by-neighborhood issue. It's obvious you've never had fiber of any type, and you don't even mention satellite or metropolitan WIFI. Cable is not the end-all, be-all internet provider.
