Headline has a serious case of "Tony Stark was able to build this in a cave, with a box of scraps" syndrome. What runs the internet today is completely different from the "hack" and more than at least 1 Netscape employee worked on it and its modern iterations.

Well, in fairness to the headline, all of the bad parts of Javascript introduced in those 10 days are still there.
