I resent Gladwell to this day, possibly because I was assigned to read him in high school. He is quoted too much -- the 10,000 hours thing is just a meme at this point, for me anyway.
I’m giving Norvig a pass here because I don’t remember it being such a cliché in 2008, and because I appreciate the point he’s making about the importance of practice. (Early in my programming education I often felt that I might just not be cut out for programming, and I wish more articles at the time had emphasized that it takes a lot of practice to become a good programmer).
