The idea that technology might be able to change the situation has been widely explored in ultra-dark sci-fi shows like Black Mirror—which, startups in this sector complain, everyone inevitably brings up. In one 2013 episode, a woman who loses her partner re-creates a digital version of him—initially as a chatbot, then as an almost totally convincing voice assistant, and eventually as a physical robot. Even as she builds more expansive versions of him, she becomes frustrated and disillusioned by the gaps between her memory of her partner and the shonky, flawed reality of the technology used to simulate him.
