Original Note:
Top CN is incorrect. Square roots of -1 exist, the square root function can be defined but requires a choice of convention. The stack post is about how calling i "the" square root of -1 is misleading, however the same thing can be said about any number, both real and complex. https://en.m.wikipedia.org/wiki/Square_root#Square_roots_of_negative_and_complex_numbers
