I think people have a binary understanding on this. Someone is either reading their messages or not. While the reality is that all the messages are read by a machine (not unlike GMail and Outlook) and anything suspicious gets flagged up so a human can read it. This obscure the concept of "reading" as most laypeople understand it.
replySummary: don't type in Claude anything you wouldn't like a human to read.
It tells you exactly what it does with your information if you ask it, including this exact scenario, and has for at least four months now (when I asked).
replyYes but you are someone (i assume because you are on HN) that at least understands this point. There are A LOT of people that use it as their confidant, expecting it to be private. There is a massive education issue going on as its not in the interest of these Corpos to make you fear sharing all your details with them. Because, then you wont get Dot or whatever Anthropic comes up with and share all your personal info with it.
replyYou're not wrong, and it may come down to this in court, but there's a difference between what people think happens, or the reasonable expectations, and what actually happens, and I think it's important to recognise that difference and why it comes about.
replyI don't think someone is an idiot for thinking that the information they type into their private Claude account is private. I also don't think people are idiots for thinking their phone is listening to them and giving them targeted advertising based on that. Both are reasonable deductions from their lived experiences. Both are wrong.
