The internet is cables and other hardware, and protocols, none of which is going anywhere. The Web, an internet application, seems to be dying, and certainly newsgroups and other internet applications have also died, but the internet itself isn't dead or dying. In fact, it's growing as the global rollout of broadband continues and the unconnected get connected.

the protocols are going if they are not enforced by a google. google was the "US" that gave you the post-WW2 "peace" on the web. The big players only follow "your" standards when it suits them.

consider mobile apps on android and apple. they are an example of internet without browser. you only get widely used standard browsers if big money sees a moneymaking point in having them.
