How dairy robots are changing work for cows and farmers

IIRC, the original conceit of the Matrix was that the computers were using the humans brains as computers. That is why they are fed and kept in a dream state - so the remaining 95% of their brain power is free to be used. This also explains how Neo can gain superpowers by unlocking his full potential.

The studio reportedly forced the change to 'humans as batteries', which in my opinion is much worse (why not cows?). I have zero proof, but I think they were concerned about overlap with a famous series of sifi novels that I won't spoil by naming, but that is currently being produced by Bradley Cooper at Warner Brothers.
