As far as cliches go, this is one of the big ones: As you get older, your memory "goes." When you hit middle age, it's easy to buy into this once you regularly start forgetting where you put the car keys or where you left your glasses. Faulty memory seems to be part of the universal human condition. Unless you are some sort of savant, it's impossible to remember everything you need to remember to keep your family going and to perform your job competently. This is why so many rely on memory aids. Far from "making people stupid," search engines are freeing them from the need to file away a zillion different extraneous facts in their brains.
