Artist and Inventor Differences

To me, an artist is someone who creates something, usually in the form of music, a painting, or a drawing in order to express themselves. Often they are created for pleasure that has no real use but to have people observe it and form their own opinions. An inventor is someone who creates a product that is like any other or someone who advances an already created product. An artist and an inventor are two terms that can intertwine as an artist is creating something unlike anything done before but it isn't used for anything like a physical technology or other product would be used. therefore I believe while closely related there is a fine line between an inventor and an artist.
