I think google made a mistake. AT&T (and Verizon too) still has a monopoly on places because of cables that were laid almost a century ago.

If someone figures out the next step of search, google could disappear quickly. AT&T, not nearly.

Google is still expanding fiber. They wired a neighborhood near me and theres a vote on my HOA to wire our neighborhood.

Google Fiber and Fi were focused on getting market incumbents to install fiber and decrease mobile data costs (respectively). They were not targeted at capturing marketshare, but purely tactical, and in that regard successful.
