I agree! But I just like using them to drive points across. Practical examples drive points across much better than some generalizations that take 10x as many words to be expressed.
exactly. so in 2150, or 2200, or someday, it will be a problem. So yes, it is a problem even today. It's kind of why you don't stand on train tracks even if there are still 15 minutes.
Future problems need to be fixed, else you end up as the countries you listed, Korea and Germany. It's not that hard

No. Never of the magnitude you suggested. The population pyramid simply doesn’t have the shape required for a population bomb the likes of which we’re seeing in e.g. Korea.
Given current and projected fertility, it never blows out the way you suggest. It gently curves. If Indians, tomorrow, suddenly stop having kids that would be the problem you suggest. But they aren’t. And it isn’t.
