Of course, we asked Robin to turn his bubble detection tools on what's going on right now with the stock market and the AI boom.

All right.

For those counting at home, two clues pointing towards a bubble, one not.

And as for the fourth, what he called the strongest predictor of a bubble, acceleration.

Stock prices for companies like Meta and Amazon, they are going up, but recently they have not been going up faster and faster.

So we don't know is basically the answer.

Yeah, that's pretty much what Robin said.

Now, there is another question that we haven't even talked about yet.

Even if we could see a bubble coming, should we try to do something about it?

As a society, how worried should we be about bubbles?

That is after the break.

And for these folks, one of the main questions is what, if anything, should policymakers do about bubbles?

Gadi Bar-Levi is a senior economist at the Chicago Fed.

Though, just to be clear, Gadi does not speak for the Fed.

These are his own thoughts.

And he has thought a lot about the question about bubbles.

It's pretty catchy.

I just want to be on the record in saying I think this metaphor is confusing.

I mean, you're probably right.

It is catchy, though.
