China is going to take over most of Asia sooner or later. It won't be like the ming dynasty but everyone will be allied. Knowing Mandarin is going to be a very useful skill, since cyberpunk level live translation won't be a reality until another 30 years or so.
How are you going to beat them if you can't speak to them? I'm already on it because it makes sense for me to do so, but even from a business standpoint it is a good decision. It takes longer for Botmericans to learn Mandarin so you guys should start immediately.
