Wong Wei Loon, you obviously demonstrated no capacity for a healthy debate. You deviate from answering other people's response and attack them personally and talk in condescending tones. You talk fluff as if your high concepts mean a thing to the specific topic. You get defensive when others have valid points which you are too proud to agree with.

If you want proof that it takes an engineer's heart/vision to revolutionize industries, just look at what Elon Musk did:

A Warren Buffet type of capitalist/businessman would not have the capacity to do so. It is not always about the money.

So don't look down on engineers, stupid.

Wong Wei Loon, engineers are the core.. business-savvy engineers made it hit critical mass. But pure business person, I doubt many can do such feat. They're probably like you spending a lot of time posting around to show off his superiority lol! :)
