Main reason for me is 100% of the time they just start driving and ask what suburb you're going to and how to get there. Like, if I knew how to get there, I'd have your job!

I'm no AI evangelist, but strawmanning it doesn't add to the conversation.

Spend 15 minutes on instrumentalism and save them from 15 years of confusion while blocking false ontological indoctrination.

Should interpretations of quantum mechanics be taught in quantum mechanics courses?

If so, how long should the instructor spend on interpretations-- just a brief mention, or one or more lectures?
