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.
Yes. Yes. Yes. And Exalted, Loved, and Adored. Critique is not the same as banning. The Child's doodle is always critiqued, which is why we say "Good Job!" to the child who shows us the doodle. The doodle is not created in a self-crafted safe space by any measure.
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.
The child's doodle is something one ca see and understand. You can even try to psychoanalize it or whatever.
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.)
The creator of this project published a website, took on volunteers to help build it, and held meet-ups to discuss it. In other words, they went well out of their way to publicise it. So yeah, at that point anyone has the right to say anything they like about it. If the author didn't want that to happen, they could have just kept it a private project, never to see the light of day.
