Freudian Robot: Death Instinct and Entropy

I was interested in further understanding the link between drawing upon the concept of entropy and converting the law of thermodynamics from one of heat to that of energy. I researched further that entropy is a law describing how nature tends from order to disorder in isolated systems. Another definition says that entropy is a thermodynamic quantity representing the unavailability of a system’s thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system. This idea of entropy further relates to notion of mechanical work or usefulness in the context of other ideas in Freudian Robot such as the idea of the Ultimate Machine. If there exists a law of entropy in the information model of bits streaming from order to disorder, then how is the overarching trajectory of usefullness in our intentions and ability to conjure up automatons or cybernetics that do “work” for us.
