This could fix my main gripe with The Matrix. ”Humans are used as batteries” always felt off, but it totally would make sense if the human brains have uniquely energy efficient pattern matching abilities that an emerging AI organism would harvest. That would also strengthen the spiritual humanist subtext.

Thats because the original script did actually have the human farms being used for brainpower for the machines. They changed it to "batteries" because they thought audiences at the time wouldnt understand it!

Wow, TIL. That strengthens my perception of the masterpiece. Thanks

That bugged me too! I decided that they actually meant "source of creativity" which made more sense.
