Sense Sonnet - Chiller

 World War III

A.I. of East, A.I. of West,

These two world superpowers got

Into cold war of which was best.

After a while the war turned hot.

Competing virus sent worldwide,

Which only humankind could get

Infected with and billions died.

Few humans left tried to reset

The two A.I. systems, but were

Unsuccessful, and each A.I.

Made more punishments occur,

Shut down when all humans did die.

World War III, no humans survived,

Earth's plants and animals then thrived.
