From globalisation to tribalisation in a trillion dollars of MMT.
Seoul is aiming for a second 'Miracle on the Han River' driven by the tech chaebols. SK is fairly protectionist as it is. Check out Naver. It helps to have your own language to geoblock tech. Japan does this too, but not as restrictively. Both SK and JP are in a tricky position. They were big winners of a globalised society, trading with the West and China. If the US bans them from trade with China and Chinese allies, they are going to feel the pinch big time, as isolated vassal states of Uncle Sam. Losing Chinese trade would be as bad for them as Brexit has been for the UK, relegating their economies.
Doing everything in your own backyard is hugely wasteful in terms of cash and resources, so the impact on the environment will be considerable. As governments are putting geopolitics before the environment, I guess climate change isn't that serious an issue after all. Global standards will go, so interoperability across borders will end and digital borders will match physical ones.
The UK is pretty much skint thanks to Brexit and doesn't have a lot to subsidise. We are now likely to be spectators in all this. Once the UKG roll out their own British standards, you're choice of tech will be drastically limited. You may be amazed at how fast things go down hill.
