Nothing at all. Its far too late. English has a tight hold on globalization. The earth is one now, and english was the language that was there for it. Could have been arabic, chinese, spanish but english hit the lotto. Most countries are teaching english and using letters. Even in China, altho they still have their characters of course, and that will NEVER go away, they still use letters at the end of the day. For texting, typing on their keyboard, all of that. Japan has it, and now china has it (pinyin), korea however is still hermit, but they'll come around.
Yea its a growing trend man. How do you think I navigate through all these random countries and never seem to have a problem communicating? English is every where. Even if they dont know english, they know some words. water, bathroom, help, thank you, food. Everyone subconsciously absorbs these words even just watching hollywood flicks, which are broadcast globally. All expats communicate via english, every single one of us, from Kazakhstan to India to Brazil to Zambia to Korea to Norway, when we're all in a bar in China or Japan or Argentina, we communicate with each other by way of english. Proof it has become the global language.
Just read the article. damn Rwanda went full english, I heard they sent entire classes to western countries like spies to obtain university level education and go back home, in return their country compensated them with HUGE brand new homes (clever tactic to have a high return rate). Someone posted a video of their capital a few days ago, man they're looking hella good. We got beef with them, but I cant knock their hustle man, their country is nice, it looks alot like Brazil now, and in the next few years it'll be first world status. It helps that they are a very small country so its easy to manage. Congo is just too damn big, its going to take awhile to start fixing the east and north. west is looking good tho, not as good as Rwanda or Botswana or Nigeria but for our size we're doing good.
