Seriously.

I think it's because of the way they see the problem domain. Both ways of seeing the problem domain look much the same.

I mean, a thoroughly explored domain and an utterly unexplored domain present much the same picture, in that...

There are not many unexplained mysteries hanging around.

Which may be translated to "The problem domain is thoroughly understood".

It's the problem of invisible stuff. You can't measure its extent.
