***This is what happens when children are allowed to use pocket calculators in arithmetic class.***
I knew a man, in the 1980s, who could do math in his mind so fast it overwhelmed everyone in the plant.
Then the company bought pocket calculators for everyone.
Within two years he could no longer do math in his mind as fast as he used to and had to rely on his calculator.
I knew a guy who was nearly a virtuoso pianist as a teenager. He studied Engineering in college and didn’t touch a piano for four years. When he graduated, he found that he could barely stumble through anything.
Perishable skills perish when they aren’t used.
