I recall watching a video about this a few months ago. Their explanation of how this doesn’t violate the law of increasing entropy was not satisfactory:
They ran a computer simulation of their model that showed 0 entropy at the beginning then a huge spike and then an asymptotic approach to a steady state value. Since the steady state value wasn’t zero they said “look entropy increased (from zero to some value) we don’t violate the law of entropy”.
The initial entropy value of zero was because of fixed starting conditions ie at fixed starting conditions entropy is zero because you’ve defined the state everything is in. Once I figured out this have waving I lost interest.
