The article complains about overuse, overuse is the opposite to "on the way out", so "No" is the correct answer to the question in the title.
Your first point is more interesting to me though. You say that he is "passionate" and therefore not "objective", to imply that we shouldn't listen to him. That idea worries me. I want to hear from people who are passionate, who care about what they are talking about. Thought experiment: if "only ambivalent people may have an opinion" and ambivalent people can't be bothered to have opinions, how many opinions will we be left with?
My point was more that he dismissed the viewpoint right away because it disagreed with something he was passionate about. I still think "no" is the wrong answer because both of you are responding to a question the article doesn't propose. The title was an eye-catcher. The article was about the hype dissipating.
And of course, because I'm not super enthusiastic my post is downmodded. The community on YC is alarmingly sensitive...
