Must all creation be judged? Subject to code review? Criticized and torn apart? Next, let us ban the child's doodle, for it is a self-crafted safe space, free of criticism and the harshness of reality.
Creative works are not delicate embers that need to be protected from the elements. They are divine sparks, each one illuminating the darkness. That light is meaningless without eyes to see it.
What I'm afraid is that there are some really powerful and valuable ideas in Urbit but they will evaporate away from humanity's gasp because there's no way to practically connect them to anything.
Also a child's doodle is something you can ignore or throw away and nothing will be lost... while this has some value in it...
(Edited because I saw they actually have an understandable mathematical formalism for all of it. Sorry for guessing otherwise.)
