Education certainly is growing towards being free online; at least one school, MIT, even puts up online notes and lecture videos that are open to the public. College is important for two reasons. The first is that by going to a college you are assured that you will be told what you need to study to be competent in your chosen profession. The second reason is that you can, hopefully, trust the information you're getting at the college. The terrible thing about the internet is they let anyone say anything they want. It can be avoided by only using trusted sources, but more often than not trusted sources are only open to people who pay lots of money or who are enrolled in a university or are part of the faculty at a university.
