Will we ever achieve world peace?

With a smaller world and lesser diverisity, yes.
With the current population and diveristy, no

I cannot imagine world peace truly arriving for at least several generations because the world is just too complicated, too scare of resources, and too ruled by clashing ideologies and worldviews to be completely harmonious. Even if a majority of powerful countries are attaining overwhelming economic prosperity and peace, it's still too likely that chains of misunderstandings, conflicts for essential resources, and dangerous absolutes from other parts of the globe would ultimately rock that equilibrium. Everybody needs to be content, or else those left out will hustle for survival at any dangerous cost possible.

We could probably achieve peace in the distant future if technology improves enough to the point that everybody is able to experience whatever they want, whether isolated or in communication with others, but only if cybersecurity is effective enough without breaching privacy or civil liberties. If everyone was raised to grow content about living in their own virtual world with enough substance to prevent them from needing to experience the real world, then there would not be any need to take from others. Essentially, I imagine a Hobbesian utopia with extremely beneficial technology and basic resources – not a world dominated by mind-rotting convenience, but rather ultra-advanced methods of obtaining food, health, shelter, pleasure, and adventure, all under a purified safety net.

Very true, Shark. It is basic human nature to disagree.
