20years??????? Really people???? Why not a millenium???? 20 years ago most people didn't have internet... When they did it was most of the time dial up... 10 years ago smartphone didn't exist and wireless high speed connection wasn't even a dream...
if broadband doesn't get vastly better in the near future and if it doesn't wireless will... It's not like the tech is not here anyway... The question is when will they change the cables pretty much and the NODs... The later the better actually since we'll have better optic cables by then... But they will and certainly before 20 years... The needs will have to be matched... Try to have an entire building watching 4k tv while DVRing a 4k movie and the kids are each streaming Netflix in 1080p and dad is trying to connect and retrieve his work from the company server for his home office...
there is goldmine to dig and if some wait too long they'll get crushed by the daring ones eventually no matter if you are called AT&T... You wait too long you lose... It happened to some companies in Europe during the transition from dialup to DSL or broadband... Big players got ass raped by small IPSs that took the risk to invest heavily in new better technology early and were ready when the needs arose for more juice in the pipeline...
