During Facebook's announcement of new features on the 6th of July (https://www.facebook.com/FacebookLive), Mark Zuckerberg compared several times the growth in social sharing to the exponential growth in the capabilities of computer hardwares, known as the Moore's Law, i.e. the number of transistors that can be placed inexpensively on an integrated circuit doubles approximately every two years.

For Zuckerberg, people will share 2 times more next year than this current year and so on and so forth... Despite the "appeal" of such a comparison, Mark ommits to take into account 2 simple parameters: (i) the process capability of a human being is limited (ii) time is a scarce resource (e.g. 24hrs/day).

Hence, if the growth in social sharing increases exponentially, this will lead in a medium-term time horizon to an overflow of information - users being not able to digest and treat all the data - and so to a depreciation of information, leading potentially to the end of digital social sharing.

To cite Moore about the limit of his law "It can't continue forever. The nature of exponentials is that you push them out and eventually disaster happens."
