This is more like installing anti-virus on your 3d printer.

I don’t want an antivirus on my (hypothetical because I don’t have one) 3D printer. I want it to dumbly print whatever it is I send to it.

I want all my tools to dumbly operate on whatever I'm working on. Imagine if lathes were required to try to guess whether you're reboring a rifle barrel and stopped themselves from running. Or if a bandsaw had to detect whether what you are cutting was gun shaped. Totally ridiculous. [EDIT: Looks like these examples were already brought up in the article, since they're obvious]

But you’re OK with a screwdriver that could be used to assemble a gun without even checking what it’s torquing? /s
