>Zero-Sum Games. A zero-sum game is one in which no wealth is created or destroyed. So, in a two-player zero-sum game, whatever one player wins, the other loses. Therefore, the player share no common interests.

>John von Neumann was a pioneer in building the mathematical framework of quantum physics, in the development of functional analysis, and in game theory, introducing or codifying concepts including cellular automata, the universal constructor and the digital computer. His analysis of the structure of self-replication preceded the discovery of the structure of DNA.
>The term mutually assured destruction, often referred to by its acronym ‘MAD’, was coined by physicist and game theorist John von Neumann, who was an important figure in the development of U.S. nuclear devices. Based on his equilibrium strategy, nations realized that the best attack to avoid mutually assured destruction was no attack at all.

>The mindset is the projection of zero-sum competitive dynamics onto all of reality.
>"My interests vs. everyone else." The division of the world into "winners" and "losers."
>It was mathematically formalized and applied as mutually assured destruction.
>It infected economics as "too big to fail" and politics as "too big to jail."
>It infected the infosphere as "lies too big to unveil."
>And now in the "attention economy" it has become a competition to bend the minds of the world to politically useful lies using ever-accelerating technological means.
>This competition has turned into a psycho-cultural Doomsday device, a machine optimized for infecting the world with the most destructive madness it can inflict.

You'd best start believing in memepunk animes. You're in one.

Have you posted this one here before or was it someone else?

Speaking of game theory and idealism:

also why did wikipedia choose a prisoners dilemma diagram with emojis in it?

imagine being so lazy you have autocomplete write your manifesto.

nice lil thing.

One interesting aspect of this is that the rules and outcomes of the game are 'common knowledge'. This means everyone knows it, everyone knows everyone knows it, et cetera. This is less intuitive than it appears, and lack of common knowledge changes the game substantially.

For example, suppose there is an island where the rule is that anyone with blue eyes must leave the night after they discover they have blue eyes. There are N many islanders, and all of them have blue eyes. However, there are no mirrors on the island, and nobody indicates to each other that they have blue eyes.

One day, an outsider comes to the island and announces, "at least one of you has blue eyes". At that moment, that information becomes common knowledge.

N days later, everyone in the island leaves on the same night. Why?

I don't understand how this outsider making the knowledge explicit changes this situation, given n > 1.
Everyone can already observe that there are blue-eyed people on the island and so it's hinted that there's an unspoken understanding that the islanders, being aware of the rule, choose not to indicate that others of their eye color and therefore exile them. Even if they came to this choice independently, it's obvious and every sighted person would have to be aware.
What difference does it make here once everyone knows that everyone knows it? In fact, if n > 2, everyone can easily deduce that everyone must know at least one islander has blue eyes, since they see one or more blue-eyed islanders (when n=3, then for any pair, the remaining person is blue-eyed). The announcement hasn't revealed new information, or forced anyone into confessing an islander's eye color.

Follow the chain of logic out to "everyone knows that...< n times > everyone knows that at least one of us has blue eyes".

Another hint: when an islander doesn't leave one night, what does it signal to the other islanders?
>>15184
My interp of n=3
Islanders A, B and C hear the announcement. s h b e means 'someone has blue eyes'
A knows that B knows s h b e, and they can observe it could be C. A currently has plausible deniability.
Symetrically, A knows B knows s h b e (possibly C). Same for B seeing A,C, and C seeing A,B, so I'll just follow A knowing B's knowledge.

A knows B knows C knows that s h b e. A can believe C has observed B, and B can believe C observed A.

A knows B knows C knows A knows s h b e. A can think C knows that A can see B.
I suspect I've reached a cycle now.

So funnily, each of the N can live in different, parallel realities. They think they understand each other, yet we have the dramatic irony of knowing they all (can) misinterpret each other's knowledge.
