A man once invented a talking piano-like monstrosity with a mannequin head that he thought would revolutionize the world.
Spoiler: people hated it everywhere he took it for ten years and then he destroyed it and himself in the same fit of rage.
I think I would go back in time and completely lie to this poor guy. I’d tell him that he needs to just live a full life and relax because we enlightened future people will rediscover his chattering doll head wife in 2016 and it will totally bring about world peace. Everyone home will have like, four of them. The president will deliver all speeches through one. They will be granted legal personhood and citizenship. A towering golden statue of him and his original model will tower over the world’s largest metropolis and bring joy to the hearts of children.
