I just ran across this on TVTropes's page "Human Resources":
In The Matrix the robots use humans as batteries! (And recycle the dead into nutrient solution to help feed the living).
- This would have been Did Not Do the Research if it wasn't that it is all Executive Meddling. The original story had the brains of the humans being used as part of a neural network for additional computing power. But the suits thought that was too hard for people to understand. So instead we get them as batteries, which is Artistic License - Physics.
So:
- Is it true that the original script used humans as part of a neural net?
- And if so, was it changed for the reason given above?
