this math shit is NOT easy
@chrisisgr8 if the academy will have it, i put forward that functions should be regarded as kiki if they have points of inflection where the second derivative changes sign and functions that do not as bouba
@chrisisgr8 this does however imply that the Cantor function is bouba which feels very wrong so maybe the definition should be broaded to define that functions that are not twice differentiable are also kiki
