I did this once by accident (bad scripting, managed to abort it,) it wasn’t too bad until sudo told me that the sudoers file had the wrong owner. I then learnt that there are other ways to become root.
OS ran for another ~6months after I re chowned etc to root.
So is this the reason that I see massive full page ads saying that WhatsApp is secure? They are worried that introducing ai will make everyone worried it can read all the messages? Or is it that just that they now have a way to read your messages?
