@patricksamphire Genuine question, why are people so concerned about this? I personally really like the browsing stuff with GPT, but that doesn't necessarily make me want to visit a website less. It's about convenience, and intentionally breaking this doesn't seem like the right thing to do in my opinion.
@ZBennoui For one, it's not just about search. It's being used to put lots of people out of jobs, by taking their writing and generating copy from it without permission. Secondly, it hallucinates. That information you're getting is just as likely to be made up as accurate. Copy writers, translators, artists have all lost jobs and income already from this. I'm not going to let my writing contribute to that.
