So, the Matrix was wrong we won't be batteries. We'll be data storage.

Interestingly enough, humans were never supposed to be used for batteries in the original script of the Matrix. Humans were supposed to be CPUs for the machines.

Most of that idea comes straight out of the book Neuromancer.

I don't recall any reference on using brains as CPUs on the book.

I think it was just humans who were wrong. Every time (IIRC) that it's been indicated that humans were used as an energy source, said indication has come from a human. Human batteries are a "simpler" explanation for why the Machines want to keep humanity enslaved, and it's unlikely that any of the humans are really mentally prepared to recognize that they're actually the CPUs (and possibly even the data storage).
