Whether or not the 10 to the tenth power to the tenth power to the tenth power decimal digit of pi exists, your editorial posing the question is unnecessarily confusing.

It reminded me of the day when my 3-year-old, proudly demonstrating his newly acquired counting skills, answered my question, "How many fingers do you have?" with the prompt and sure reply, "Nine, Dad."

When asked to explain, he very obligingly but somewhat condescendingly counted out loud on his digits, "One, two, three, pi, four" and continued on the other hand, "five, six, etc.," thus clearly demonstrating the correctness of his answer.

While his method was unimpeachable, and his fund of knowledge surprising (the subject of pi and circles had come up casually months before), the subtleties of integers and cardinal numbers, to say nothing of numbers irrational, imaginary and transcendental, awaited his grasp.
