What does it matter if it's true? Many artists won't even know if it was true or not, because, for the many of the most revolutionary ones, the recognition only comes many years after their death. For others, it may never come, due to confluence of irrelevant factors (let's say they were writing in a very niche language). If the artist believe in what they're doing, whether or not people recognize it is secondary and not something they should worry about too much.
