The US will be copying Asia in this case. China already has super apps like this and Grab & GoJek already expressed their interest in following their lead. US is way behind.
I believe GP's statement on international apps was sarcastic and subtly pointed out that this technological siloization would foster narrow worldviews.
Language silos our world view more than tech could. If you read a news article about Greece that isn't in Greek, chances are you are reading a cherry picked one off story that the newspaper thought might be of general interest to English speaking audiences, leaving behind an entire reality that is invisible to your world view, having never uttered Greek to steep yourself in the most thorough relevant information, or even been to Greece to see it all for yourself. The Greece you've constructed in your head doesn't even exist.
Yes. Western people really can't understand this. Western media can publish only negative facts about some country and this creates completely distorted world view. They don't even have to publish fake news (although they were pioneers in this also).
Centralised platforms like Google also contribute to this because they can (and in case of Google they do it indeed) lift up negative articles and bury positive.
The world is already siloed and narrow minded and always was. E.g. OP writes "evil countries like Russia, China, Iran". It's a very narrow view that is very far from truth. It is formed exclusively by western media and nothing else where another evil country - US - tries to defile every other country in order to loot it using direct (invasion) or indirect (sanctions and neo-colonial politics) measures.
