No Stupid Questions

That's another rule. No wishes containing the word 'all'. Guaranteed ironic consequences.

I don't think anyone's going to miss wars.

Star Wars, Thumb wars, wow, Storage Wars!

As long, there are rankings in society, money, and power and human emotions – conflict will never end.

Impossible. There is 1-5% of the population who are born anti-social. It's very difficult to socialise them, and some never do. They are vastly overrepresented in prisons. These people sometimes get into positions of power. Particularly in societies which value authoritarianism, like Russia and China. This cannot be helped. Instead, we must mitigate the effects of their reach. NATO, for example, is an excellent way to stymy these dictators.

Implantation of the post-scarcity society and the end of capitalism ez gg

Economic democracy; if money and resources cause wars then why not let everyone have control? I will probably hear the human nature stuff but being social is just as if not more important than hurting your species/society.

An unfortunate combination of somehow achieving a post-scarcity, non-capitalist society with robust resource and population control.

But people are greedy and want "freedoms" that run counter to this.

Humans need to evolve to a state where love, compassion and being helpful to others is ingrained. At the moment we're just clever beasts.

Sadly though, I don't think we have enough time.

Very easy. Global thermonuclear war. That should make sure that the remaining humans (if any) don't need to fight over resources for at least a few generations.

this is a bit grim but global-wide information control that shreds any information which will help the growth of the idea of overly patriotic but less enough to not kill the domestic culture (but i think, not necessarily always telling the truth). that will also promote the sense of global village and transnationalism. and relocate the idea of war to other rivalries like on sports or something, idk.

basically limit the free will without showing it. I can't think if it's gonna happen or this even possible.

Well effectively, it would entail an all-encompassing global spying machine that gathers all data possible, and imprisons anyone who deviates from the expected baseline. (Wouldn’t end well for me either.) You have to remove most individuality to remove reasons for fighting. And even if you imprison 999 false leads to capture just one instigator, that’s the only way to ‘guarantee’ a fairly high level of security.

So what I’d say we need is 1984 or Мы levels of oversight to have any chance of curtailing conflict for good.

It would take way more but the first step it would be to remove religions. And not only because most are not peaceful in principle but also because some religions see others as a target. Even small difference in beliefs could spark a vicious and long standing conflic, like Catholics Vs protestants.

Simple. We make war illegal.

Humans are gonna human unfortunately. Biologically I’m not convinced we are capable of eliminating war because humans are competitive by nature. To the point that there will always be one group or another trying to force its ideals onto another.

I’ve often thought about “what if we could snap our fingers and every weapon beyond that of a spear (technologically) was vanished, and any/every attempt to fashion something deadlier would fail/poof out of existence as well.”

That might stave off large scale war but there would still be tribal warring on a smaller scale I fear. Plus a ton of other issues that would arise from suddenly having no guns/missiles/projectiles/etc.

Establish a global trade network in a way that everyone is completely dependent on everyone else.

The only way to end all wars is for all people to fully control the instinct of domination with rational mind. It's all about education and self-awareness. Making people rational creatures

I think the solution is to have enough renewable energy for all of humanity.

Kill every human, or all but one. As long as there’s at least two people, there will be conflict.

If you see war as a struggle to get access to scarce resources and if you notice that currently humankind is depleting most of the available resources then you might come to the conclusion that if in the future we will not need to go to war something terrible must have happened. Are you sure about the future you want?

Education for everyone globally. War is, like all kinds of violence, an act or reaction of impotence (psychological term/not sexual).

It basically means nobody actually chooses to act violently or start wars. They do it because they believe consciously or subconsciously that they have no other options, because they can't think of any options.

This is always a wrong assumption, because there is always a better option. The difficult part is to getting people to understand their actual options. Education solves this.

Create an Artificial General Intelligence with the sole purpose of satisfying people's values through friendship and ponies.

Make the old men fight each other and soilder just refusing to follow orders that seem stupid

Easy enough, we just build a jail so big that we can fit the entire world inside of it, boom no more crime.
