Addiction as Entrenchment

Any explanation of human behavior involving brains and their chemistry can at best be parochial. Since our computers are universal, we know that they could run any algorithm the brain runs. A computer can, in principle – although we don’t yet know how to program it to – run whatever algorithms make a person, including an addict. A computer made of metal and silicon has neither a brain nor hormones nor any other allegedly relevant chemistry, yet it could still simulate an addict. (Here, ‘simulate’ does not mean ‘fake’ or ‘mimic’ – it basically means ‘give rise to’, ‘instantiate’. A computer running such a program would literally contain a person.)

So the prevailing explanation violates computational universality.
