Would it be ethical to read someone’s mind or is that the only true form of privacy?

I believe it is unethical! I hope it doesn’t happen in my lifetime here on Earth.

I could be embarrassed if someone was reading my mind for sometimes, I am talking to myself how this person is going on and on and repeating the same thing then I don’t even really hear them at that point. I do this instead of being rude out loud. If they laugh and I really didn’t hear, I laugh. 🤪
