What a 1980’s tech maroon!
To even get DSL it takes one of two things. You must be within 18,000ft of the TELCO Central Office or that close to a SLICK Cabinet which is fed by a Fiber Optic Cable. See any cables being buried? AT&T knows something is coming but it is still about a decade away for nationwide usage. Landlines will be gone and airwaves are the replacement. What is holding it back? Several things including the auctioning of enough frequency spectrum to handle such a system.
AT&T isn't going to develop it but they will own the switching at least from office to Cell Tower. The cell companies to make this work will have to increase their tower grid substantially which takes time and money. The fastest way will be a lower orbit say at about 2000 miles satellite system which will handle most comms and internet. The current orbit of the birds Hugesnet uses are 20,000 miles out and make telcom next to impossible but works for Internet. As of right now they don't have a system in place which can handle what's coming.
Technically it can probably be said most persons have access to high speed internet service. Much of that though would be including I Pads etc relying on Hot spots etc. My cell phone even here in the rural area has some Internet capabilities.
The companies are putting out gear that many places are not ready for and in some areas overtax existing resources. Windows 8 is about 5-10 years ahead of technology in many places even in urban areas.
You'd think they'd notice no one is upgrading the grid needed to provide national high-speed broadband at the speed needed.
You forget something else. Cable Companies made a mad rush to come in and run Minimal Service meaning a few miles into some counties and thus getting no competition contracts. That means no incentive to expand and no one else can come in. COMCAST is less than a half mile from me. I've called, neighbors wanting service have called, etc. They don't care. Now pay closer attention. Ma Bell must by law run you a landline for phone services and can not charge you for how many poles or feet of cable used. In walks Cable who sells it all and is free to do as they please. AT&T knows better than to do others upgrades.
