Article suggesting that the amount of information we produce/learn must by nature have an upper limit, and we are not far from reaching it. Comments? Thoughts?

The Information Catastrophe

Melvin M. Vopson (University of Portsmouth, School of Mathematics and Physics, Portsmouth, UK)

Currently we produce 10 to power 21 digital bits of information annually on Earth. Assuming 20 percent annual growth rate, we estimate that 350 years from now, the number of bits produced will exceed the number of all atoms on Earth, or 10 to power 50. After 250 years, the power required to sustain this digital production will exceed 18.5 TW, or the total planetary power consumption today, and 500 years from now the digital content will account for more than half of the Earths mass, according to the mass energy information equivalence principle. Besides the existing global challenges such as climate, environment, population, food, health, energy and security, our estimates here point to another singularity event for our planet, called the Information Catastrophe.
