We make allowances for mental deficiency in our justice system, be it from congenital mental retardation or sudden psychotic break from reality by other means. I'm arguing that alcohol is one of those other means. We know that there is a segment of the population who cannot control their drinking once they start, cannot function rationally while intoxicated, and often cannot even remember their actions while intoxicated. Yet, alcohol remains legal for adults to consume, while other drugs with this profile are banned from casual use.
Having seen psychotic breaks from hard drinking up close, I can't make the direct link from someone starting drinking and ending up drunk driving and say that it absolutely isn't an accident. I've seen drunk people doing things far more unlikely than driving a car. I wouldn't hold them blameless, but neither would I claim clear intent, either.
Instead of having computers in everything, I'd rather have robot that checked the milk and all that. What we're really all hankering for are slaves^H^H^H^H^H^H robots shaped like human beings, that we don't have to feel sorry about exploiting. They'll do all the things we don't want to do and won't require everything in the house to have a battery in it. I'd much rather deal with a single robot than worry that every appliance in my home has a brain and its own agenda.
