I've been working with many MNCs and climbing corporate ladder through out my career life without mandarin.

I've been successfully purchased goods from taobao, without knowing mandarin.

I've been to China few times too for work without mandarin being spoken.

In fact until today i've been communicating with PRC on a daily basis in my line of work ...without mandarin.

So I'm good.

It has some interesting points though, especially the part where it dispels the myth that it is a "door opener", when in fact, it actually isn't.

yes, that part is true, but that doesn't make the video any less dumb.
people who choose to learn any language without doing any research into how it will benefit them honestly deserve to have their time wasted.

yes. but from my projection of /k visitors which are mostly pakatan troopers, most likely 85%+ of the people will agree with the thread starter and talk about how important things is and about how english is superior, well covered, etc.

The argument in the thread is good. however, the author forgot that the moment you kutuk this language, DAP supporters will rage.
