Where it comes to Internet access for billions of people who do not presently enjoy it, pessimism is unwarranted.

Significantly, Internet adoption increasingly is at an inflection point, promising rapid adoption in the near future. Granted, at the moment perhaps 60 percent of humans remain unconnected. But change is coming fast.

India and China are important, since they represent such a large percentage of the unconnected. Those two countries represent 54 percent of all the people remaining to be connected.

Between 2011 and 2014, in India, Internet users doubled.  China, for its part, has seen adoption rates adoption rates far faster than virtually any other country since about 2006. Mobile Internet adoption has grown from about 66 percent in 2011 to 89 percent in 2014.

In fact, just 20 countries account for 75 percent of the 4.4 billion people yet to be connected to the Internet.
