> Very soon, "meat space" will be the only space where one can interact with others and know that the thoughts flowed from a human brain and aren't simply the result of someone prompting an LLM to "write a rebuttal."

And even that’s being optimistic. I lost faith once I heard that there are people honestly using ChatGPT to ask what to order at a restaurant! If large tech companies like Facebook get their way, you’ll soon be having your smart glasses¹ listen to the conversation, transcribe it, write a response, then show it to you on the lens so you can reply. And that’ll be just for the ones who want to fake it by still moving their lips, because the others will have voice (trained on their own) come out of speakers. “Smart” devices will be having conversations with each other while you are served ads.

¹ The royal “you”, not you literally.
