This article is avoiding terminology, data and any specifics on the problem that it renders it useless.

You might be fooled it says something useful if you don't know what a 'model' means in any science.

So what is the point of the article? The author is trying to sell you his book where he most probably makes people who don't know anything about economics feel good or push an ideological agenda.

It's not so much useless, it's just far more general than the author probably intends.

All his arguments apply equally well to any scientific models which require fitting, in geophysics (as he acknowledges), atmosphere/ocean science, climate modelling, most of biology, ecology, etc.

Why he singled out economics is beyond me.
