This is the type of thing that I sort of rely on HN to inform me about. Then other articles are seemingly killed as dupe which I guess would make sense if the original was visible.
I’d liken it to going to a hacker conference and wanting to talk to like minded people about 3D printing something controversial, like a gun barrel or a knife. It’s interesting as a topic and worthy of technical and moral exploration but putting it on stage as a keynote talk would risk attracting all the wrong attention.
