What is happiness?

[TimeShaper]

I suppose that personal opinion is an alien term around here.

Technological evolution gets a 1000% boost during wartime. And war is, of course, caused by hatred/xenofobia between nations and/or races.
We would hardly evolve while everybody is happy and there are no needs. We would stagnate.

Why do I have to be considered as a troll/raging kid just for seeing things from a different angle?

Insane troll logic...

Trolls don't bother to think.

Actually, the only reason people do these things at all is to achieve happiness.

Exactly, it doesn't really matter whether happiness exists or not, as long as we don't have it we will advance. So we don't need it. Not yet.
