maplebots, grey goo
me: "grey goo that turns everything into maplebots"
laser: "augh, no!"
me: "grey goo that... only turns other electronics into maplebots?"
laser: "but... my data!"
me: "sorry, your hard drive is a maplebot now. she still remembers everything, but now you have to ask her nicely"
laser: "don't... don't look in that one folder..."
me: "you've scarred her for life."
