Some day I want it explained to me why it's impossible to put controls on a computer. Computers follow symbolic mathematical rules, so, "you're only allowed to run this app for 30 minutes" seems like a really easy command to follow. But you cannot buy software that
actually, reliably causes this to occur at
any cost on
any device.
It seems like there are three hard things in computer science: cache invalidation, naming things, and forbidding things.
