central claim in this book is that these two trends—overprotection in the real world and underprotection in the virtual world—are the major reasons why children born after 1995 became the anxious generation.

real world,” I am referring to relationships and social interactions characterized by four features that have been typical for millions of years:
They are embodied, meaning that we use our bodies to communicate, we are conscious of the bodies of others, and we respond to the bodies of others both consciously and unconsciously.
They are synchronous, which means they are happening at the same time, with subtle cues about timing and turn taking.
They involve primarily one-to-one or one-to-several communication, with only one interaction happening at a given moment.
They take place within communities that have a high bar for entry and exit, so people are strongly motivated to invest in relationships and repair rifts when they happen

They are disembodied, meaning that no body is needed, just language. Partners could be (and already are) artificial intelligences (AIs).
They are heavily asynchronous, happening via text-based posts and comments. (A video call is different; it is synchronous.)
They involve a substantial number of one-to-many communications, broadcasting to a potentially vast audience. Multiple interactions can be happening in parallel.
They take place within communities that have a low bar for entry and exit, so people can block others or just quit when they are not pleased. Communities tend to be short-lived, and relationships are often disposable.
