Granted! 4 remains the exact same. But 3? Oh man, 3 is now 5. But wait! 5 is now 2 and 2 is now 15 and 15 is now pi and pi is now 1 and so on until all the numbers are changed to strange and, in many cases, unknown values save for 4. 4 remains exactly the same. Mathematics as we know collapses. And if Mathematics collapses, so to does physics followed shortly by chemistry and so on until all the math based sciences, of which there are numerous, shatters. Uncountable years of advancements fall away in the blink of an eye. But the number 4 remains exactly the way it is.
I wish to be gone with the wind.
