Do you really think Will Scott gave the DRPK the breakthroughs it needed in any of those areas? I think you would be delusional to think he set them up to significantly improve in these areas. The only thing holding the DRPK back is the fact the socio-economic situation in the country is in complete shambles. Not that lack of American Computer Science teachers.

Plus, More than likely he (and others like him) are providing intel or participating in espionage on behalf of Western Governments.
