The author appears to run this website: https://learncodethehardway.org/ https://learncodethehardway.org/ which directly profits from people not doing bootcamps but rather, teaching themself to code (using his books). So maybe not the most unbiased source (even if some of the content rings true). Everyone - everyone - always has an angle.
