Money is not a representation of value. It is a representation of desire. I agree that, in principle, an economy does not have to be set up as a zero sum game, and at smaller scales (many of us don't realize that 1 billion is relatively small for global scale economics), it really doesn't have to be. I agree that value can be created. But value doesn't run this economy, desire does. And sometimes desire runs totally counter to what is _actually_ valuable.
Not to mention that, especially in a fiat environment where currency is printed out of thin air, it is literally a zero-sum game by definition. When the printer winds up, the bankers win big at everyone elses expense; setting the tone for the entire market. Anecdotal success stories of hard working, honest billionaires is a nice distraction, but that's all it is.
The substantive reality of the status quo is one of unprecedented levels of extraction, and as we continue down this AI power consildation story, that will be harder and harder to deny as we go forward. If you happen to win big as an outlier, more power to you, but the article even admits to the rarity of this story implicity. 20 years. thousands of companies. 30 billionaires.
Even if every single one of those people are honest to goodness saints, that's only slightly better odds, perhaps, than winning the lottery.
Don't forget this is from the group of people who get an extraordinary helping hand in the form of YC and all that represents, and of businesses hand picked to be the most likely successes. And even then, it's still just winning the lottery.
