What is the universe computing?

Over the years, it has been debated in the meta-popular culture that we might be living in a simulation. I wrote about this “Matrixical” notion earlier. And again, Seth Lloyd from MIT, asserts that the universe is a computer.

So if the universe is a computer, what is it computing? Its own evolution, apparently, according to the laws of physics. That might not be too obscure actually, because the most general definition of the term “computer” would be “a system that takes a set of input and deterministically produces a set of output.”

Overhead, without any fuss, the stars were going out. What do you reckon?
