It's always sad to witness this need to flatten things on a space of two extrema. Often it's a complex combination that can't be pinned down neither in space nor time.
It actually oversimplifies all four dimensions, if you can even claim with any surety that there are exactly four dimensions. There are things like "third gender" [1] and there are demisexuals [2] and there are asexuals and so on.
What I like about it is that it's just slightly too big as a concept presentation (though it feels like it isn't) and mostly evokes the recognition that There Are Things You Didn't Know About.
