Some people are considering that there will appear essential barrier on the way of developing the Internet: bandwidth. Yes, exactly, the bandwidth. The number of users will be so big that the existing channels will not be enough for them. The existing power of Internet.
It's really so, lots of people feel some slowing down, which are appearing in a some period of time. For example after work or at 9 PM. Everybody are sick of the constant Twitter's "pressure of work". Facebook has problems too.
This is true, that everyday the number of Internet users is increasing. And with every next day their number will be increasing more and more. But now, there are making some works about cabining through the ocean and testing of the new technologies. Unfortunately I can't tell the technical details or loud names, but i'm sure that in this sphere everything is just beginning. The answer will come. Our planet will be overloaded sooner than Internet.
I would rather think about the first one...
