Yes! This is the nature of our species. We externalize thought. Calculators make people dumber. A slide rule is like a trombone; you slide to your best guess, then listen to the sound and home in on the note. An abacus trains the mind to no longer need an abacus. In the future the most capable humans will be those who coevolve with external tools. This has long been the case, but we're entering a realm where those tools are increasingly cognitive. Mathematics is a nice microcosm for the tension here: It attracts people with unusual gifts who are certain those gifts are sufficient to proceed as if today is 1790. Others, perhaps not so gifted, but with a greater brain plasticity who welcome these external tools, are having a field day.
