Sure, but how is this different from a human "intention"? All human intentions are just chemical/thermal/electrical changes interacting in a physical substrate to mindlessly "pursue" a different "goal" of chemical/thermal/electrical states. Unless you think the chemicals inside a brain are conscious and therefore willful or intentional!
