John ChapmanNobody believed Chapman in 2005 when he outlined a path to gigabit cable. Speeds were 10 or 20 megabits. Your cable modem today runs at a gigabit. He led the DOCSIS 3.0 program that got us there and now is going to 10 gigabits. It's just reaching the field, with Comcast starting to install tens of millions.

John sees cable speeds reaching a terabit in 2040. He gave the keynote at the Cable Next-Gen conference. I doubt anyone there believed him, but he has been right many times before. Jeff Baumgartner, the best reporter in cable, has the story. 

He's one of the best I've met in 25 years of tech reporting.
