So far, machines have a pretty hard time emulating creativity, arbitrary enough not to be predicted by a computer, and yet more than simple randomness.
And I think that being able to choose based on other characteristics, than merely the arbitrary fact that you're a member of this community is important, otherwise it's left to, I guess, randomness.
In 1795, a new simpler method of measurement called the metric system was invented and aimed to take a lot of the randomness out of things, so they could be measured more evenly.
