"only imposed ourselves to the extent that doing so doesn’t suppress the ideals of others" does not equate to "If no one attempted to turn their ideals into reality".
What if people's ideals are already being imposed? People will always be oppressed, not even by another's idealism, but from the greed, control, and need to expand.
For example if I wanted to be the creator of strong-AI I'm free to do so, because nobody has the explicit ideal that I don't, and even though others may have the ideal of becoming the first creator of AI they have no right to stop me, after all I'm not suppressing them, their failure to be first is their fault and theirs alone.
You are still going to create discord. People would lose jobs now that they can be replaced by a machine with Strong AI. The competing manufacturers of the last strongest AI would lose money from being beaten out by a new competitor. A change that massive would probably be good in the long run, but it will definitely impose itself on others, even if it is indirectly.
Sounds unnecessarily violent, but we're accustomed to it aren’t we?
Of course we are accustomed to it, it is how we grow, it is how we have always grown. What you are trying to illustrate is a completely impossible scenario. Idealism is just a part of human nature, and it has taken us as far as we have come. The American Revolution, The French Revolution, The Civil Rights movement, all of that came from idealism, and it has massively increased our standards of living. People were and are being oppressed, and the only way to stop that was and is to fight. They weren't really even fighting other ideologues, but tyrants and greedy aristocrats.
You're assuming one's survival is dependent upon another's death.
So am I to assume you think cannibalism & murder are natural?
It is, sometimes it's human beings, some times it is animals, sometimes it is just plants. But life cannot sustain itself without taking life, that is just the nature of nature. And yes, murder and cannibalism are natural, if it wasn't natural it wouldn't happen. One cannot be above nature, if a kind of behavior is commonly occurring, then it is in our nature to do this.
Really? (were are you getting these supposed facts of yours?)
I posit that a society without conflict is inherently more efficient & cooperative, thus overall it'll be healthier, happier, wealthier, and well, just better.
Really? You're seriously going to play the 'where are your sources' card? Same place you are getting yours, fucking no where, it's a philosophical debate.
Okay if you can get everyone to magically agree on everything and act as more of a hive than a society, then yeah, I guess it would be more efficient and cooperative. Your idea is like communism, sounds great on paper but it could never realistically work that way; and as ironic as it is, it is naive and idealistic to think it could work on a massive scale. Secondly, a society like that would never advance because it has no incentive to. Not to mention the change of advancement would introduce a certain chaos into the society that would surely create some sort of conflict. A society like your could exist on a small scale, however if you asked me which is a more successful community: a Small one where everyone was happy, and a massive one where conflict exists. I'd say the massive one, the key to a species survival is expansion, and if we are doing it then we are doing something right.
Also you strawman me by saying society would be without ideals, I'm not saying that, I'm saying society should be without idealism, which is having ideals and trying to impose them upon the world without regard for the ideals of others.
Again, you run into the snag of getting everyone to agree on everything. In order to advance, you have to impose your will on others. Yes, this certainly creates conflict, but it yields what we have now, the most successful species on the planet.
