However,the reality is that most people simply can't do it. Take an average office and try to teach everyone how to code. after a month, 99% will know how to output text to console, 10% would probably be able to write a loop or two and maybe 1 or 2 guys will realise that development is their real calling. Those 2 guys will spend the next 5-7 years just to get to the point where people would start taking them serious and some senior engineer may even listen to what they have to say about system design. Writing a simple web based calculator is easy, however doing a proper enterprise level solution isn't something any bootcamp student gets anywhere near without 10 years of experience..
