He's the most documented person in earth, and the recent influx of... meddling weens proves that his shenanigans are interesting to newer generations.
Like it or not, he's a pretty iconic part of a very... colorful part of the history of the internet, one part that I'd suspect will always have a strong nostalgic appeal, and that will only get stronger with time. To many people Chris is the Avatar of the last days of the "wild west internet", the last lolcowboy. He will not disappear in a long time, and I'd say he'll survive as a sort of urban legend when everyone interested on him today are dead.
