I'm trying to think of a time humanity has tried to do this with an emerging technology and I'm drawing a complete blank.
Imagine pausing during the industrial revolution. Your country would be completely left behind. Internet era? Even worst.
It also occurs to me that in each of these technological changes, there is an educational leap that your populace has to make in order to be competent with the new technology. Schools were standardized and reformed to produce good factory workers. The curriculums were adjusted to make students at least functionally competent with computers.
It seems reasonable to believe that a pause will not just leave you behind economically, but to recover it will take a generation of students to be properly educated before you can actually harness the technological change.
