Knowledge is the thing that makes the existence of resources infinite.

The creation of knowledge is unbounded.

We're just going to keep on creating more knowledge and thereby learning about more and different resources.

There's this wonderful parable of European in the beginning of infinity where

David talks about 60 years ago or so when the first color television started to be manufactured,

they were cathode ray tube type where you'd fire a stream of electrons at a phosphorescent screen.

And the phosphorescent screen have these pixels, three different colors.

One of which was red and those red phosphores on the screen were filled with the element European.

And the interesting thing about European is when you put electricity through it, when you excite it,

it glows with this red color.

And the extra interesting thing about European is that it is the only such element on the periodic table.

It's the only chemical that will do that.

If you fire electrons at it, it will glow the red that you need to have color television.

Now, it was calculated that there's only a certain amount of European on the earth.

And that amount of European was quickly being consumed by cathode ray tube manufacture.

So the scientists had a perfectly robust mathematical theory about how the number of cathode ray tubes was finite.

Therefore, we're going to run out of cathode ray tubes.

And it's true in a very narrow sense that for any given resource,

you're going to have a finite amount on planet earth.

Of course, there's going to be a European in outer space and you could probably mind it there.

But the deep point is no one has cathode ray tubes anymore.

The whole idea of color television has nothing to do with the excitation of European these days.
