I want to keep participating because there are some very good, very well thought out responses here, and some with very good advice. However, there are a lot of posts by people who either haven't read the thread, misunderstand the premise of the thread, or are simply misinterpreting the original question. There are many assumptions being made here and I don't have the time or the will to address them all.
Let me explain my initial assumption this way:
I've never met a film student whose SOLE career goal was to do remakes of his favorite films. I've never met a sculptor, an illustrator, or a painter, whose SOLE ambition was to learn to recreate the masterpieces, without any desire to create original works. Based on that, and my consideration of music as an art form, I think it's a perfectly reasonable and valid assumption that people who pick up an instrument do it for artistic reasons, or is music not a form of art?
Many of you assert that you picked up the bass with no intention whatsoever of creating your own music, therefore my assumptions were wrong. I accept that. I personally know several violinists, saxophonists, and pianists who would never attempt to create something in a million years, but I hadn't thought about bassists in that sense before. Bass isn't an instrument you're forced to play at school. It's not an instrument you play because your parents pressure you to. People play bass out of their own enthusiasm. I know that music is an art form whose practitioners study and rehearse for years to improve and maintain their technique with no intention of creating original works, I just didn't believe that Bass Players would start out that way.
