I notice this weird hostility whenever the topic of AI coding comes up and it's never made much sense to me. If someone told me about their new method for practicing guitar I'd feel like a real tool if I demanded they prove it for me then and there.

You've made your ideological position very clear here, you don't need to keep heaping it on.
