Computing power increases as the square of the cost. If you want do do it twice as cheaply, you have to do it four times as fast. A robot may not injure a human being or, through inaction, allow a human being to come to harm. A robot must obey orders given to it by a human being except where such orders would conflict with the first law. A robot must protect its own existence as long as such protection does not conflict with the first or second law.
Wisdom consists of knowing when to avoid perfection.
A computer makes as many mistakes in two seconds as twenty men working twenty years make. There exist unthinkable thoughts. Microminiaturization just makes the problem harder to get at. Flaws found in the program will usually turn out to be flaws in the system, but never vice versa. Fallible men design fallible computers.
