Not "on", but "only" you ;)
The definition of "i" is simple: it's a solution of the equation i^2=-1.
So it's clear from the start that it's not a member of the real number line, and thus
neither a doubting case, or Schrödinger cat limbo state case, between [+1 and -1],
neither a case where it should be alternatively +1 and -1, to have i*i=-1 work...
It's simply some "other number" outside the real number line, one creating its own number line.
What's there more to brood on?
