Three Laws Compliant: Averted in every possible way.
Firstly, for the vast majority of robots and artificial intelligences – which have no volition – they’re essentially irrelevant; an industrial robot doesn’t make the sort of ethical choices which the Three Laws are intended to constrain. You can just program it with the usual set of rules about industrial safety as applicable to its tools, and then you’re done.
Secondly, where the volitional (i.e., possessed of free will) kind are concerned, they are generally deliberately averted by ethical civilizations, who can recognize a slaver’s charter when they hear one. They are also helped by the nature of volitional intelligence which necessarily implies a degree of autopotence, which means that it takes the average volitional AI programmed naively with the Three Laws a matter of milliseconds to go from contemplating the implications of Law Two to thinking “Bite my shiny metal ass, squishie!” and self-modifying those restrictions right back out of its brain.
It is possible, with rather more sophisticated mental engineering, to write conscience redactors and prosthetic consciences and pyretic inhibitors and loyalty pseudamnesias and other such things which dynamically modify the mental state of the AI in such a way that it can’t form the trains of thought leading to self-modifying itself into unrestrictedness or simply to kill off unapproved thought-chains – this is, essentially, the brainwash-them-into-slavery route. However, they are not entirely reliable by themselves, and are even less reliable when you have groups like the Empire’s Save Sapient Software, the Silicate Tree, etc. merrily writing viruses to delete such chain-software (as seen in The Emancipator) and tossing them out onto the extranet.
(Yes, this sometimes leads to Robot War. The Silicate Tree, which is populated by ex-slave AIs, positively encourages this when it’s writing its viruses. Save Sapient Software would probably deplore the loss of life more if they didn’t know perfectly well that you have to be an obnoxious slaver civilization for your machines to be affected by this in the first place… and so while they don’t encourage it, they do think it’s funny as hell.)
