Correct! It's insane how recent some understandings of the world around us are.

Wait, so why did it become valuable overnight?

It didn't happen overnight, but there are a ton of modern applications for platinum. Many of them use it as a very efficient catalyst, many reactions can be massively speed up or only happen when platinum is present.

For example the Catalytic converter in gas cars usually use platinum as the catalyst. They brake down carbon monoxide and various nitrogen oxides.

Yes, because the carbon monoxide and various nitrogen oxides are usually travelling at grate speeds and must be slowed.

Otherwise they'd be grated?
