A letter from May 19th, 2021

Hi there, hope you're feeling better and safer. I just wanted to remind you, since we might not have the same diary by now, that tomorrow is the day that Heinz von Foerster's model predicted that human population would reach infinity (see the wiki page for Doomsday Argument). Feeling crowded yet? See you now (from your perspective), 2021!Asa
