It’s all well and good to “advance the art”, but don’t expect to become rich doing it. The real geniuses are those that can push the envelope and engage the multitudes. Anything else is just singing to the choir.
What do you mean by “pushing the envelope”?
Making advances in the art or science. For example, CGI is an advance in movie making and it's getting better with every cartoon movie. That's an advancement of the art that isn't just "art for art's sake", rather everyone benefits from it. In contrast, making a movie that only 5 people can understand may be "pushing the envelope", but it's only to the benefit of a handful of people.
