So I wouldn't say it's obsolete, but you are right that some things you learn in "hacking courses", are obsolete and shouldn't really be included, but they're good "fillers", which is equal to: money.

I was at a Starbucks the other day and thought of this thread. Some kids had been outside doing chalk art and I thought back to my CEH training and thought, "Well whatdya know, War Chalking!"
But you're absolutely right, some of these certs seem to think they're being paid by the weight of the book.
