Hong kong sincerely need to develope science, technologies, engineering and maths, STEM is always the fundamental base for a sustainable growth city. Hong Kong relied too much on opportunistic, fast track of money making, and put us in to strog dependence on others. As mentioned, this is why Hong Kong transportation network is so strong yet this lies a hidden trap signing we are too weak to grow on our own. Hong Kong should develope and look into other fields of industry!!
