I hope this doesn't derail the conversation much, but I found it interesting that you seem to be using 5 digit years, a convention I've never seen before. What drives this choice?
it turns out it's sort of like wearing a mohawk. a long now mohawk. it's a completely harmless deviation from convention which provokes an amazing variety of reactions, some astonishingly aggressive, while other people react thoughtfully
Thank you. I hadn't drawn the parallel before. But that matches my experience with both.
