I think I read it like you did first, that fining him billions would be more than half of his net worth, which is wrong.
But I think they mean that if you have billions, taking away half wouldnt change your life. I’d also say thats wrong for musk though because his money is tied up in companies. If he had to pay a cash fine of a huge amount, that likely would cause discomfort.
While I disagree that “billions is beyond being halved”, there is some truth to the idea that numbers can get so big that halving doesn’t make much difference. That seems very very counter-intuitive, so I’ll try to briefly explain.
Consider (10^10 + 2). That’s 10000000000+2. I think it’s fair to say that the +2 doesn’t make a lot of difference. It’s still approximately 10^10.
So then, consider 10^(10^10)×100. That’s a huge number, too big to type here, then multiplied by 100. So the result is 100 times bigger than the huge number. But… writing it down we see this:
10^(10^10)×100 = 10^(10^10+2) ≈ 10^(10^10).
So although ×100 does make it one hundred times bigger… that just doesn’t really make a lot of difference to a number as big as that one. As numbers get bigger and bigger, they start to take on properties a bit like ‘infinity’. Addition stops being important, then multiplication, then for even bigger numbers exponentiation doesn’t huge much of an impact either.
Mathematically, I think this is really cool and interesting. But I don’t think 1 billion is that big. 10^9 is big enough that +2 doesn’t matter much, but not so big that ×2 doesn’t matter.
[edit] (I’m struggling to get the nested powers to look right… So hopefully my meaning is clear enough anyway.)
A single billion, when put in terms of money, is enough that - simply invested in GICs and bonds, earning a very, very conservative 1% interest - it would earn you ten million dollars a year in interest alone.
I would challenge you to even come up with a reasonable way to spend ten million dollars a year. By my back of the napkin math you could vacation every single day, living in hotels and eating at fancy restaurants, and still not make a dent in that.
Musk has an estimated net worth of $247 billion. You could fine him 99% of his current wealth, and he would still struggle to spend enough that he wouldn’t end up increasing his remaining wealth every year.
Not really billions is beyond being halved
Hi I’m a mathematician.
What’s the actual fuck are you talking about?
I think I read it like you did first, that fining him billions would be more than half of his net worth, which is wrong.

I’m a mathematician too. They’re probably speaking from an intuitive grasp of utility.
I think they’re just saying that if you’re a multi billionaire and get a 50% net worth fine, you’re still a billionaire once it’s done.

Maybe posting a picture where you write it out? I think I understand though.
Interesting concept, thank you!
Have you ever played idle champions of the forgotten realms? At some point you start to get this feeling.
Happens in MMOs too, world of Warcraft was bad with it over the years on and off.
They’ve reduced the numbers down multiple times so that people start to feel progression again.
They’re not talking about Maths. They’re talking about wealth.
division has no power here old man!
