A decade is nothing. If issues will be worked through a decade from now, that means the best time to think about opportunities/coonsequences related to that is now.
North Korea pretty much only uses the Internet for scams Or to make money in violation of sanctions. They certainly don’t allow their citizens to use it for anything else, and they don’t allow their citizens to leave the country because they would never come back.
Even if it were only temporary, suddenly cutting off the Internet to the country would expose all of those remote workers to the people who employ them and don’t realize they are employing North Koreans when they all disappear at once.
Is this just not logistically feasible? or are we just too afraid it would be unpalatable to our allies? I can’t be the first person who has thought of this.
