Gretchen’s journey ended seaside. The roiling clouds of the machines gathered at the horizon, scrubbing away the blue skies. Her blue bike, the last loyal machine, had carried her a thousand miles over broken asphalt, but gave out in the end. She reminisced as she walked that last mile to the beach. In her lifetime, she had lost good friends, two husbands, and both children.
But the sadness of their loss did not wash away the joy of their memory. She had given birth to a million lines of code and two sons, and shared uncountable laughs and international coffees with friends long gone. A thousand moons was time enough to understand that all things ended. So it was with mankind.
Gretchen settled herself onto the sandy bank, letting the timeless ocean lap at her sore feet, and breathing salty air into her aching lungs. As the sky darkened, gusts of wind cut through her woolen overcoat and babushka. The swarms of molecule-sized machines had been fruitful, and multiplied, and now they had subdued the Earth.
Unnatural dark clouds encircled the last remnants of blue sky. Directly overhead, the faintest sliver of the Moon smiled down at Gretchen. Close parenthesis.
