  > Comcast isn't building new last mile infrastructure, they're using new modems on both ends of the coax cable. In a lot of places, they're also adding lots of equipment in the last mile to shrink the "node" sizes so that the number of households within any particular shared medium on Comcast is much smaller today than it was 10 years ago. It's not the same level of build out as bringing fiber drops to every home, but it's also not nothing.
