I think of technology as offering a sliding scale for how much assistance it can provide. Your words could be literally the keys you press, or you could use some tool that fixes punctuation and spelling, or something that fixes the grammar in your sentence, or rewrites sentences to be more concise and flow more smoothly, etc. If I used AI to rewrite a paragraph to better express my idea, I still consider it fundamentally my thoughts. I agree that it can get to the point where using AI doesn’t constitute my thoughts, but it’s very much a gray area.
