This, but with machines.

Humans are draining and there isn't much positive coming from them, so overall rather negative.

Animals are neutral, though need upkeep which cant be ignored, so maybe slightly leaning towards overall negative even.

Machines on the other hand, those serve a purpose, even though those do need maintenance and prayer, generally the purpose those serve is simple and useful enough to be worth the effort of dealing with those, in addition nothing happens if those are forgotten for a while.
