This is in relation to the ‘say more’ part, not specifically about the halting problem or P/NP. Since computation is physical, there are theoretical bounds on the energy consumption of computation. (Landauer’s principle [0]). Physical limits computation are at least one way to think about the relationship between thermodynamics and software.
