Well, you reach first for this immense tool you have, the most flexible and creative problem-solving device on the planet — the intelligent, educated human brain.
It’s like you take the massed brainpower of an entire country, and with one stroke you lower the total of usable I.Q. by half. That’s like the difference between an I.Q. of 150 and one of 75. Between genius and borderline mentally challenged.
Ha! Think that has no side effects?
Any society that does such a thing, I can’t imagine it has much of a future.
