Perhaps one day people will be able to mate with shapes. Imagine your second cousin is actually half square. The logistics of getting down with, or settling legal battles against different types of figures, rather than people, is something outside of the conceptual realm of what we're touching on in this review.
Shapes have been breeding since, quite literally, the beginning of time -- do you think the sun was born round? No, that's preposterous. It took millions of years of degrading genes and square reproduction to eventually lead to what we now know as a circle.
The time has come for us, as humans, to step up to the plate and, as I crudely stated earlier, get down with our ancestors. Who knows what'll come out of it? I mean, no one expected Uber, right?
