Idea: Futurama-style "s**cide booths" that don't actually kill you but instead use AI and brain scans to convince you NOT to commit s**cide. Also: it could generate a "It's A Wonderful Life" or "A Christmas Carol" movie on-the-fly which is customized to your life; if it made people feel too good they'd want to stay in the booth forever; you could inject a timed poison in their body which can easily be removed so they have lots of time to back out if they regret their decision; crazy sci-fi future tech could eliminate many of the reasons for s**cide
