I still can't put my finger on why seeing a lonely robot wandering around after mankind has gone extinct makes me feel bad for the bot, but I'm pretty sure it's not the "mankind going extinct" part.
Perhaps it comes down to how much I and others like me we relate to that feeling of loneliness we take with us wherever we go, or maybe I'm just a sucker for a lonely robot story.
Whatever the reason, Redone by David James Armsby made my engine purr, even though the conceptual short introduces us to mankind's doom...
