Context collapse is a term used to describe how information used to be divided into different parts of our lives, but now it all exists in one place, like on the internet. For example, when you're at school, your teachers and classmates might only know you as a student, but if you're on the internet, your teachers and classmates can also see all kinds of private things about you, like photos from your weekend or things you post about your family. It can be hard to keep track of who sees what kinds of information about you, and it can be tricky to keep different parts of your life separate.
