I think they demonstrate a welcome and sophisticated understanding of technology. Their solution to age verification maximizes privacy by not sending any data off the computer besides a simple signal of age category (if I understand the design). They show more sophistication than the parent commment:
> 3D printers should have a magical algorithm to recognize all gun parts in their tiny embedded systems
Color scanners and printers have long had algorithms to recognize currency and prevent its reproduction, implemented with the technology of decades ago. It seems relatively simple to implement gun part recognition today, especially with the recent leap in image recognition capability.
(Rants and takedowns, IME, may entertain fellow believers, but signal a comment that's going to go well beyond any facts.)
