There is a general principle here that contradicts the naive idea “why remember things when you can just google them?” Because remembering is faster. And because it’s not an either-or. Things you carry change your brain, and the change is not as simple as a function atrophying through simple outsourcing. The cowpaths a thing-carried wears out in your brain are a mix of amplified and atrophied capabilities. Sometimes you might actually amplify a capability by outsourcing it to a thing-carried, through a sort of Jevon’s paradox effect.
