Do You Have a Long List of Things to Remember?

Socrates warned that writing might be harming memory more than 2000 years ago. And the worries that people have today about smartphones and other kinds of digital memories I think can be seen as the latest iteration of some of those same worries. So in my view a lot of these worries are really unfounded. We all know short term memory is very very limited in capacity. You can only remember four things exactly. If you can't chunk them into bigger units just four individual items at once in your short term memory. It's very verylimited in capacity.
