Any interaction I have with anybody at any time I can't necessarily assume that it's going to be private. If I'm giving a talk in a class in the old days you know you assume it's your interaction with the class but it can be on social media and somebody in a remote part of Russia could be seeing it the next day. And even when a group of people get together in a residence or in a private space so-called it could be recorded and replaced. So there are, you know there are really important questions about how do we protect privacy that we need as as individuals to have places where we can develop our ideas where we can try out ideas we're not on public not performing publicly, not engaged in public uh discourse but we're working out our ideas and talk about them. A lot of people refer to those as safe spaces. I think it's really important to have spaces where we have intellectual privacy, where we can explore ideas amongst friends or people who think alike and and so what happens when those kinds of spaces disappear because of how common and ubiquitous recording technologies are or recording devices are.
