A long term future of shoebox apartments?

Is it too far fetched that we will in Year X, where X is quite a big number, shoebox apartments would be the norm? Unthinkable now but completely logical.

The driving force toward that is both simple and inexorable. All modern economies are addicted to growth. With shoeboxes like those in Hong Kong and Tokyo, the critical limit to cramming more people in our 700 sq km would not be space but water and energy resource.

I hate to think about such a future and I bet this blog would no longer exists come Year X.
