That it's a bit, yes.

So if you aren't terminally adhered to one of the stupidest subcultures in the broader tech sphere, that probably does seem like nonsense.

And it is.

But let's start with the bit about paying someone 300 grand to write about what a human's utility function is.

Now, what is a utility function?

Behind the Bastards
CZM Rewind: How Sam Bankman-Fried Conned the Crypto World & The Sam Bankman-Fried Update

Great question.

In economics, a utility function is the measure of welfare or satisfaction of a consumer as a function of the consumption of real goods like food.

In simple terms, it's a way of describing the satisfaction or other benefits gained by consuming a specific resource.

This is important to rational choice theory, which is a theory that states that individuals use rational calculations to make rational choices to achieve outcomes aligned with their own objectives.

Now, most people who aren't economists think that talking about the economy this way is silly because people are not, in fact, rational actors.

And in fact, we make shitty decisions all the time guided by misinformation or pressure that causes us to inaccurately interpret the potential value of something like a college education versus the cost of, say, student loans.

Right?

CZM Rewind: How Sam Bankman-Fried Conned the Crypto World & The Sam Bankman-Fried Update

Wonderful example of the irrationality.

Behind the Bastards
CZM Rewind: How Sam Bankman-Fried Conned the Crypto World & The Sam Bankman-Fried Update

Humans are not rational.

But...

Behind the Bastards
CZM Rewind: How Sam Bankman-Fried Conned the Crypto World & The Sam Bankman-Fried Update

That's economics.

Behind the Bastards
CZM Rewind: How Sam Bankman-Fried Conned the Crypto World & The Sam Bankman-Fried Update

This is not an economics podcast.

Behind the Bastards
CZM Rewind: How Sam Bankman-Fried Conned the Crypto World & The Sam Bankman-Fried Update

I'm not an economist.

Behind the Bastards

And the way that Bankman Freed and his fellow EAs talk about utility functions is not the same as how economists talk about it.

Behind the Bastards
CZM Rewind: How Sam Bankman-Fried Conned the Crypto World & The Sam Bankman-Fried Update

Right.
