Hmm, ok. Let me retry.

The digits of pi are not proven to be uniform or randomly distributed according to any pattern.

Pi could have a point where it stops having 9’s at all.

If that’s the case, it would not contain all sequences that contain the digit 9, and could not contain all sequences.

While we can’t look at all the digits of Pi, we could consider that the uniform behavior of the digits in pi ends at some point, and wherever there would usually be a 9, the digit is instead a 1. This new number candidate for pi is infinite, doesn’t repeat and contains all the known properties of pi.

Therefore, it is possible that not any finite sequence of non-repeating numbers would appear somewhere in Pi.

Prove that said number isn’t pi.

OK, fine. Imagine that in pi after the quadrillionth digit, all 1s are replaced with 9. It still holds
