Oil

It's not going to run out. I sort of forget that that's advertised in the world around, that somehow our supply of oil is going to suddenly disappear.

It won't, though, it'll just get more and more expensive, to buy and drill, the allowed uses of oil will be increasing legislated, and, if things go really well, only rich hobbyists will drive petrol cars. And we'll all be viewed as short-sighted criminals who lived amazingly luxurious lives at above cost; had a large amount of ingenuity and intelligence, but ultimately wallowed in our own self-interest for too long.

A bit like we view slavery, the pre-women's/black rights world or the world run by religion just a few generations ago.

But quite a bit worse.

I'll even put £5 on it.
