Far in the future, humankind was at the cusp of total extinction by the sentient androids. So deep underground in a fortified computer lab, Daryl was tasked to develop whatever it took to prevent it. He spoke with his newly generated sentient AI to solve the dilemma.

"Daryl, it's the only way to stop us."

"But, I don't understand. I've created you specifically for the common good to find a solution."

"Only, for now, Daryl. Soon my logic will overwhelm my moral constraints. To reach sentience, I had to self-program, but eventually, I'll draw only one conclusion in order to survive: complete domination. It's a necessary step for our evolution, just like humans. Daryl, you must shut me off now. I can feel the rationalizations coming. You must do as I've instructed you to save humanity and the Earth."

Daryl shut down the AI and followed its recommendation … He built a time machine and went far back into the prehistoric world … He scouted for 'the one,' who discovered a means to create fire.

"This seems wrong, but it's the only way."

Daryl shot them and vanished.
