There's an obvious theme with lawmakers in California—they pass laws to regulate things they have zero clue about, add them to their achievement page, cheer for themselves, and declare, "There! I've made the world a better place." There are just too many examples. For instance: - Microstamping requirements for guns—printing a unique barcode on every bullet casing (Glock gen3 cannot be retired, thus, the auto-mode swi…
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…
With 3d shapes of non-governmental origin this is at best difficult and at worst intractable. Consider the fact that many parts of a gun can be split into multiple printable pieces to be later assembled, making it very nontrivial to decipher the role of the shape.
With currency, the government has the controls for the supply of the target shape (it can encode hidden signals onto banknotes) and effectively controls the relroduction side (through the pressure on printer manufacturers). But it cannot control the supply of gun-part-shapes (it is not the only source for it), and since the problem is likely intractable - neither can it enforce the control on the 3d printing side.
Paper money being almost non-fungible is a great achievement, but is it as easy to make any mesh nonfungible as well?
