Worries about information overload are as old as information itself, with each generation reimagining the dangerous impacts of technology on mind and brain. From a historical perspective, what strikes home is not the evolution of these social concerns, but their similarity from one century to the next, to the point where they arrive anew with little having changed except the label.
These concerns stretch back to the birth of literacy itself. In parallel with modern concerns about children's overuse of technology, Socrates famously warned against writing because it would "create forgetfulness in the learners' souls, because they will not use their memories." He also advised that children can't distinguish fantasy from reality, so parents should only allow them to hear wholesome allegories and not "improper" tales, lest their development go astray. The Socratic warning has been repeated many times since: The older generation warns against a new technology and bemoans that society is abandoning the "wholesome" media it grew up with, seemingly unaware that this same technology was considered to be harmful when first introduced.
Are you under the impression that what you presently believe about privacy/identity/morality/anything is special?
Your brain is wired to tell you that it absolutely is. Your brain will tell you that its experiences are more important than any other set of experiences, and it will call your experiences "truth."
This is perfectly fine, so long as you recognize that this applies to everyone else's truth as well.
