I chuckled at first, but it doesn't seem so far-fetched. This is a story of a startup founder backed by y-combinator, who posthumously provided inspiration for a memorial bot[1]

WhatsApp (Android) stores it's backup on Google Drive by default; by using this data, it is more than possible to create a bot and resurrect someone in the digital domain.
