comment What is the opposite category of $Set$?
@Pece if they are not functions what are they, I understand you can view functions as set of tuples $\{(x_0, y_0), (x_1, y_1)...\}$ and in ${Set}^{op}$ we are just inverting the order of x and y? But then how do we treat the morphisms from $\emptyset$ to other sets?

@AsafKaragila haha that's funny but not very helpful.

@ZhenLin but the opposite category has to be able to be instancable right? The morphisms in ${Set}^{op}$ has to be some concrete function I assume...
