What if, in the distant future, everyone understands that this newest generation at the time WILL be the final generation of humans, so no one has first names, and instead they’re referred to as “The Final ____” (e.g The Final Williams, The Final Smith, etc.) and they know that the end times are nigh, so they live their lives knowing that the universe ends with them. Possibly a Highlander-esque battle may ensue, who knows?
