The article didn't go into much detail about how all this was calculated out. I don't think they took into account gov debt. that can be a huge factor. Japan for instance has not had any increase in GDP over the last 25 years and that doesn't look like it's going to change. So I don't see how their gdp can jump from 4.8T to 7.2T in just 11 years! Japan is currently at 230% and it weighing very heavily along with their aging population. Their GDP hasn't been increasing at all in the last 25 years. The US is heading in the same direction with budget deficit of 4% every year whilst only growing 3.3% a year. US interest payments are expected to reach 25% of federal spending in 2028 if we continue with our current deficits. At that point, unfortunately US growth will be a complete standstill, for decades to come :( Indonesia is an interesting one to watch, i keep forgetting how much people are in that country!
