Interesting, but tricky to wrap your head around 🤯

We'll have some prices falling faster than others.

- Some items (esp. technologies) will become better while decreasing in price only slightly.

- Other items (e.g. apples) will be an unchanging product and hence decrease faster, at about the same rate as new value gets created elsewhere in the world.

- Completely novel categories (e.g. flying cars) will add new value and push all other prices down.

So we could estimate GDP growth to be roughly equal to the rate of price decrease of the apples category.
