The internet at its current growth rate and development stands to be the greatest machine ever built in the history of humanity. This machine also happens to be the most reliable machine human beings have ever constructed. It has never crashed before and has always run uninterrupted. Consider the usage of the internet too.
There are over 100 billion clicks per day online, there are approximately five trillion links between all internet pages in the world and over two million emails are sent per second from all around the planet. The internet also accounts for five percent of all electricity used on the planet to keep it running continuously.
An approximation of the internet in terms of size and complexity resembles the way a human brain would function. The internet however is continuing to grow in size and complexity every two years. At the rate at which the internet is evolving, it is projected that by the year 2040, the internet will be able to store more knowledge and information and be able to operate at a higher level of cognisance than the whole of humanity combined.
