The First Law of Complexodynamics (Aaronson)

June 21, 2024

-why does "complexity" or "interestingness" of physical systems seem to increase with time and then hit a maximum and decrease, in contrast to the entropy, which of course increases monotonically?

Kolmogorov complexity - for an object, the length of the shortest computer program that produces that object as output

-how could a system not tend to evolve to more "generic" (probable) configurations? if it didn't, those configurations wouldn't be generic!

-why was it ever low to begin with? why did the universe's initial state at the big bang contain so much order for the universe's subsequent evolution to destroy?

-entropy is an upper bound of complexity

-how can something be complex if it is not disordered?

-entropy/complexity at the beginning are both low

-complexity at the end is low because of equilibrium
