Ultorg (SIEUFERD) is amazing and inspirational research, and I'm glad to see that it's finally available to the public after all these years. It's one of those things that really makes you sit up and take notice of how much better our everyday software could have been.

However, I wouldn't be willing to try it under proprietary-software terms. Last week, I was thinking about eliciting open-source software with the Ultorg look and feel from an LLM, thus replicating the author's HCI research and enabling other HCI researchers to build on it, which won't be possible under a proprietary license.
