Was not easy. If I had to do it again, I'd like somethings changed in the next version. The universe is benign most of the time. Catastrophes are anomalies, but they suck big time when it happens. Got to make sure they do not happen. My ancestors did an OK job within their limited knowledge and cognitive biases. Some of them were ahead of their time. I'd like to thank them for their balls which I think I have inherited.
