He originally played with it in a Black Mirror-style fantasy about using reanimating his favourite grandparent. “What if I could have him back?” It was a thought experiment for a while but then he thought, “what if I just tried?” And he did. He found his favourite photo and clicked the button. His Grandad was dead, he knew that. He wasn’t resurrecting so much as reimagining, remembering in a more powerful. No Black Mirror questions. But now he was reanimating others from his past: a girlfriend, his former business partners. They were alive but now he could reanimate different decisions.
