The analogies to prior technologies aren't insightful. The advent of LLMs has some similarities to the appearance of the internet, and very significant differences. Calling it a "tool" is also far too reductive. What kind of tool that existed before just writes everything for you? Is that the same kind of tool as a nailgun or a text editor? The "proper usage" that has to be learned is to learn to think for yourself before you get used to the word-bot doing all the thinking for you.
