Redundancy’s a benefit in smart
design, along with sensors and alerts.
And symmetry’s a necessary part,
aesthetically and practically. Then hurts
are not catastrophes. Malfunctions do
occur, but engineering kept in mind
the likely fails and rarer problems too,
so long as it was thoughtful and refined.

But overload the system, or impose
a heap of insults: then the whole is wrecked.
And no thing is more elegant than those
machines we call our selves. We can’t expect
endurance from corruption and disease,
or peak performance from deficiencies.
