I don't disagree, but I think even just setting it to 500M symmetrical would be a MASSIVE improvement and a more achievable goal. Few regions right now are equipped for fiber and even fewer homes.
Most homes in the US have a coax connection, and with current tech coax connections can do a little over a gig bandwidth total (up+down). That said, we should be quickly ratcheting up to 500/500 while the fiber rollout hopefully accelerates.
