Place and routing compilers used in semiconductor design are not. Ironically, simulated annealing is the typical mechanism and is by any appropriate definition, imo, a type of AI. Whatever you do in your life using devices that run software are proof that these tools are effective for continuing to scale complexity. Annoying to use also ;)
