I'm glad to see people discussing [zero,infinitesimals,false,emptystring,isnull,unpopulated,missing] as if each one is a thing. They've always been things! We've just been buried in compromises and shortcuts all these years.

There should also be a [the-asteroid-has-hit-y'all-are-so-stupid] and global data systems should just just pass that around after impact until the power goes out for good.
