Difficult is not equal to impossible. Heat can be used to boil working fluids, which can be used to drive turbines, which can create energy, which can in turn be used to run AI chips, which give off heat, which can then also be harvested to boil working fluids...Not really a perpetual motion machine, but the inefficiency in the system can be used to suck more heat out of the heat pumps anyway. Inefficiency in this case is a feature.
