Hilarious. They were right to do the comparison, but got it oh so wrong.

I was recently trying to understand Elon Musk's wealth, and come up with similar comparison: For example, he could make millionaire's of every single person in Seattle, and still have hundreds billions of dollars of wealth left over. Truly mind boggling.

Elon doesn't have a pile of cash, and it wouldn't be possible to convert his assets into cash either (without an incredible discount). This is true for most billionaires. In fact this very fallacy is part of what I'm alluding to with "we need to educate better".

So while fun thought experiments are excellent selling points, they aren't actually grounded in reality.
