I was wrong. I shared it with peers, and posted about it on some social media and link-aggregation sites, but it basically went nowhere.
I didn’t understand. “Don’t they see what kinds of interesting possibilities this opens up?” (spoiler: they didn’t)
It reminds me of Bret Victor. Lots of people talk about the future of programming or the future of education. The thing that made Bret different is that he demoed it. It didn’t matter that his demos weren’t fully built, or available for anyone to use. We simply needed to see it, in order to understand.
Nothing speaks like a demo.
