This is a very good computer story for 1948. It could have been used as inspiration for Collosus: The Forbin Project. It was used in part for the 1954 movie "GOG". Gog and Magog were robots used to kill in both tales.

GOG probably isn't a bad movie for 1954 but I wouldn't recommend it today. The book is much better. But the stories are of a government computer installation for mostly military purposes. In The Brain the computer becomes conscious but in GOG it gets taken over by "foreign" agents.

The way The Brain is overcome is quite amusing though.

There is a streak of sexism in it but it's 1948, what do you expect. I actually like it better than Neuromancer. It is the first story I know of where a computer is depicted as rising to consciousness.
