Stories of a short, fat bastard.

The swapping of the second and third laws lends itself to all manner of problems. If a robot decided that to protect its existence it had to take over the world, then it would happily do so and there would be mothing anyone could do about it. Sure he'd make certain no human was harmed, but it wouldn't be all that nice for humanity. Which leads me to the problem with the first law, that being the definition of 'harm'. It effectively means that your expensive robot would be helping everyone it met no matter what you had ordered it to do. It could be argued that unless the robot did something about it, all those people consuming large amounts of alcohol and having a jolly good time were actually harming themselves; so the robot just better take care of all that for humanities own good. A sort of Puritanical enforcer. :8)
