What am I looking at? It appears to be a collection of comments from StackOverflow back in 2008.<p>Nothing in there says "Either your interest in coding starts at a young age or not at all". There is a plot of "distribution of ages when starte programming", but that's self-selected from the population of people who answer questions on Stack Overflow.<p>If so, a better interpretation (IMO) is "Early Stack Overflow contributors started programming as teenagers."
