One thing that is guaranteed to occur, is that the US Government will regulate the Internet to a greater degree every year that goes by. It's what they do with all segments of the economy, and that regulation has been accelerating for decades. Tech had been largely spared, but the Feds have been increasingly pushing their nose into every area of tech the last decade.

What will ultimately happen, is the government will regulate the Internet so tightly, it will become extremely difficult, time consuming, and costly to create a start-up (while the technology cost will continue to fall). This process will not be fought by the existing tech giants, because they will think they benefit from it by limiting competition with artificial barriers. It's the exact same thing that has played out in every other major segment of the economy, and it's exactly what is about to happen to the Internet. These days will be viewed as the unregulated wild west, when you could spend $50 and create a start-up without hardly a concern.
