I'm in KC and am also skeptical if Google can fully pull this off but they have laid down A LOT of fiber. They've contracted to Atlantic Engineering and many are seeing their trucks all over the city actually stringing fiber through the manholes. I see them about every other day at different intersections through Midtown KC - with giant roll of fiber. Two months ago they've reported over 100 miles strung, is likely quite a bit more than that by now.
Even if Google doesn't manage the network in the end, KC is getting a _major_ infrastructure upgrade.
and if they don't get it launched- the fiber will be nothing but sitting there unless its sold to someone or some ISPs decides to lease it. The same as with other cities that have Fiber deep within in. It's useless with nobody using it.
