What we stop doing when tools change

When calculators showed up, people stopped doing as much mental math.

When mobile phones arrived, people stopped memorizing phone numbers.

When the internet became mainstream, we stopped remembering every little fact as everything could be looked up.

Now, with AI, all answers are one chat conversation away and agents can even handle work on our behalf.

Every single time, the prediction has been the same: “This will rot our brains.” And every single time, reality proved to be different, cognitive load just shifts from low-value tasks to higher-value ones.
