Stanley Wu Posted almost 3 years ago Education system based on useful knowledge I don't know, I mean who's to decide what is useful and what is not? As a recent engineering grad, I've learned to appreciate all things that I've learned because I've learned to be a competent engineer, it is enough to be good at what they do. But to be a great one, one would have to be at least knowledgeable about all aspects of life. Including things that we do not usually associate ourselves with. For example, Da Vinch was an inventor and an artist, I think we could be missing out on a lot of stuff once we start deciding what is useful and what is not.
