Our entire civilization is built on non-zero-sum cooperation. Technology is the byproduct of non-zero-sum cooperation.
If you're going to try and argue against game theory, your going to have to bring a much better argument.
Silicon Valley is built on the attention economy. That term is a euphemism for making people spend their waking hours on addictive crap, taking away from the useful sum total. That's my definition.
Competing for people's attention is a zero-sum game, but building technology that helps people be more productive and do new things they couldn't before is not zero-sum.
Are you accusing me of redefining the meaning of life to be dollars? If so, I completely deny that accusation as it doesn't remotely align with my beliefs or what I said in my comment.
Certainly value isn't zero sum, as we can always change our minds and value something else more, but I don't think this is a good argument for life (or wealth) not being zero sum. Anything we create, takes energy or resources from elsewhere (zero sum). Every path you choose to go down in life, is a path you didn't go down (zero sum). Simply put - everything has a cost. Sure we may not value costs equally (not zero sum), but remove our arbitrary valuations for things from the equation, and it is zero sum.
