The next step in human evolution?

Well... no, it is already quite difficult to determine what a 'step' is, so this is not the next step in the human evolution, but it is actually an idea I gathered from reading different sources... so basically is just focused in this analogy I am building up right now...


If a single-celullar being took millions of years to learn that grouping armoniously with other single-celled organisms was both a huge advantage and a high risk, but that has been worth it; how much time will take us, humans as 'individuals', to realize that competition is counter-productive, and that the next step in our own evolution is to bind ourselves as one being, as our cells did millions of years ago?

Of course, we can work in group, and as a team too, but to be honest, we are behaving more like rats, than like a cohesive group or team: at the first sign of trouble, the rats leave the ship abandoned to ill fortune. A cell cannot do that... to be part of a multi-cellular entity, means that the cell has to have ultimate commitment: If the cell next to me dies, I die as well...............; but we, as humans, just wander around like single-cellular automata, learnt, by force, that competition is the way to go, that the one that has more money/love/friends/success/internal knowledge of itself/whatever adjective or sustantive you want to put here, is the best
