Entropy describes the number of internal states a macroscopic system can occupy for a given set of conditions like temperature and total energy.

“what it really describes is a macroscopic system has many different internal states it can be in and entropy really just describes how many internal states a system has for a given macroscopic configuration of of say temperature and overall energy”

Maintenance acts as a counter-measure against the Second Law of Thermodynamics by preventing complex systems from degrading into equilibrium.

“if entropy always increases in a closed system, the ultimate end state for anything is just equilibrium, right? You know, the temperatures all smooth out, everything becomes kind of boring. The kinds of things that are complex systems doing interesting things, whether they're mechanical or technolog”
