I love Steve Martin, and has as much respect for his talents as I do just about anyone.
Think about how diverse of an artist he is for a second. He started his career in show business as a teenage magician who was good enough at magic that he actually performed it for a living. He managed to land a spot on the Smothers Brothers writing staff and eventually won an Emmy. He decided he really wanted to focus on performing, specifically stand-up, and then he became, arguably, the best stand-up comedian ever. He co-wrote The Jerk and starred in it, a movie generally regarded as one of the 100 funniest movies ever made. He moved fairly effortlessly between dumb comedies to romantic comedies to serious comedies, he writes very dry and very funny pieces for The New Yorker, he authors two novellas which are sad and funny and beautiful in very subtle ways, both of which receive pretty good critical reviews, he writes a memoir about stand-up comedy that is universally praised, and he's also written plays that are both commercially and critically successful.
Throw on top of that the fact that he plays the banjo well enough that he actually released an album of original recordings that went to No. 1 on the bluegrass chart.
I'm not sure we'll ever see another artist like him.
