Fame
If you grew up in the U.S. any time since the late 1980s, you've heard of at least two sculptors, although maybe not in the proper context. If the names "Michelangelo" or "Donatello" ring a bell, it's not only because they're the best Ninja Turtles (and they're definitely that).
Two of the greatest artists of the Italian Renaissance period, Michelangelo Buonarroti and Donatello Niccolò di Betto Bardi, studied the techniques of ancient Roman and Greek sculptors and improved upon them, laying the groundwork for all future sculptors―even those who design and make the TMNT action figures. That's what we call "full circle."
So what are your chances of achieving historic fame or getting an anthropomorphic cartoon bunny superhero named after you? Pretty much none―unless you know Stan Lee, that is. Those sculptors, and others like Rodin, Camille Claudel, and Picasso are famous because they were revolutionary at a time when that didn't mean a new iPhone was coming out.
Fame now is much more low-key and specific. You don't typically find world-wide acclaim, but if your ideas start approaching the never-been-seen, you'll probably find your name in an art magazine every once in a while.
