You’re not wrong, but you’re not right either. For whatever it’s worth, I absolutely plan on self hosting (nvidia Digit!) my future conversation partner. But nothing about me is terribly private. I love my wife and my sons and sometimes I wonder if I’ll be forgotten or if we’re about to give birth to the overman. It’s nothing I wouldn’t tell a stranger.
Lastly, no therapist I’ve ever met can talk about my favorite authors with me for hours, ad-hoc, on-demand, for pennys a day. All my real friends are sick of Dostoyevsky, but not Claude!
