> Well, let's put it another way. How much chemistry or physics education can you get from a teacher who has never learned enough about their own subject to figure out how to build something like a pipe bomb?

Probably a decent amount, honestly, and certainly enough for a "high school ... introductory physics or chemistry class." I mean, what does high school chemistry cover? Balancing chemical equations, Arrhenius acids and bases, basic lab work, and other very basic stuff like that? Someone can excel in the class by carefully reading a textbook that certainly doesn't cover bomb-making. It's not like students are going into novel applications or anything.

> Just about anyone with a basic education can figure it out if they're put to the task...

Without a recipe or off-the-shelf explosives? I doubt it. Or we're a nation of MacGyvers and I had no idea.

And even if true, a teacher who hasn't put themselves to the task of building a pipe bomb can be a perfectly good chemistry teacher. These models can't figure anything out, they just regurgitate and associate on command. There's no reason they need to have inappropriate content irreverent to their purpose available to regurgitate. Leaving a student who wants to build a pipe bomb in the situation of having to put themselves to the task of figuring it out from the basics themselves, instead of having their homework-help model effortlessly regurgitate it for them is fine.

> And this is just an example. The same goes for thousands of other topics in hundreds of other fields that would be inappropriate for teachers to teach. If you shelter them all from the world to the point that they're completely ignorant of the forbidden topics, they would be ineffective as teachers. A school full of those teachers would be ineffective as a school. A society filled with such schools would be stunted as a society.

To be blunt, I think you're going off into la la land following generalizations and tangents.
