The inefficient machine

The previous post made me reflect more about efficiency.

Let imagine exist a machine:

The machine need at least one hour of warming out, cleansing and energy input each day before can function properly. Plus at least another hour at the end of the day

It have to be idle at least six hours each day.

Quality of output is distributed almost randomly among machine (even the almost identical one) and one machine tomorrow’s output can be totally in different quality from today.

The paint on the machine sometime cost more than the whole energy input over its productive time.

A machine has ability to destroy (and has been seen to exercise it) other machines, even the whole factory.

It survive by destroying lesser machine.

Would you acquire such machine?

Thankfully, God (or/and evolution, which ever you prefer) choose to have such an inefficient machine, some call it human, roam on earth.
