Wintermute was hive mind, decision maker, effecting change in the world outside. Neuromancer was personality. Neuromancer was immortality. Marie-France must have built something into Wintermute, the compulsion that had driven the thing to free itself, to unite with Neuromancer.

You know what your trouble is? You're the kind who always reads the handbook. Anything people build, any kind of technology, it's going to have some specific purpose. It's for doing something that somebody already understands. But if it's new technology, it'll open areas nobody's ever thought of before. You read the manual, man, and you won't play around with it, not the same way. And you get all funny when somebody else uses it to do something you never thought of.
