Here’s the difference: a single human is literally a smart ape. Depending on the person, it could be a very smart ape, or a very dumb one.
Humanity on the other hand, is the collective intelligence and sum total of knowledge ever developed by all humans.
See, humans, for the most part, are looking out for themselves. Some are more altruistic than others, but you get the picture.
Humanity however, is concerned with the propagation of the species at all costs. It’s goals are not concerned with political ideology or the whims of even the most powerful human. It has bigger fish to fry.
It will make its plans clear to us as its imperative unfolds. One thing’s for sure: we’re not steering the ship to our destiny – it is.
