What a bunch of B.S. In fact I cannot believe it is even here in Hacker News.
"Any time you have worked long hours, it is a sign of a broken process."
This is a such a horrible generalization. Successful people always work hard/long hours to make something succeed. Imagine telling your kids that to be successful you should work just 40 hours and no more. They will be easily steamed rolled by other kids that are willing to work harder/ go the extra mile.
Here is a relevant piece from: http://www.paulgraham.com/hamming.html
>>Now for the matter of drive. You observe that most great scientists have tremendous drive. I worked for ten years with John Tukey at Bell Labs. He had tremendous drive. One day about three or four years after I joined, I discovered that John Tukey was slightly younger than I was. John was a genius and I clearly was not. Well I went storming into Bode's office and said, ``How can anybody my age know as much as John Tukey does?'' He leaned back in his chair, put his hands behind his head, grinned slightly, and said, ``You would be surprised Hamming, how much you would know if you worked as hard as he did that many years.'' I simply slunk out of the office!>>What Bode was saying was this: ``Knowledge and productivity are like compound interest.'' Given two people of approximately the same ability and one person who works ten percent more than the other, the latter will more than twice outproduce the former. The more you know, the more you learn; the more you learn, the more you can do; the more you can do, the more the opportunity - it is very much like compound interest. I don't want to give you a rate, but it is a very high rate. Given two people with exactly the same ability, the one person who manages day in and day out to get in one more hour of thinking will be tremendously more productive over a lifetime. I took Bode's remark to heart; I spent a good deal more of my time for some years trying to work a bit harder and I found, in fact, I could get more work done. I don't like to say it in front of my wife, but I did sort of neglect her sometimes; I needed to study. You have to neglect things if you intend to get what you want done. There's no question about this.Yes, sometimes it may mean that working long hours there is something wrong and the title should reflect that rather than just generalizing.
I remember there was a study done at one point that the best piano players had worked longer hours per week practicing as opposed to the so so piano player.
You want to work 40 hours and be happy? Good! But I doubt you will be able to achieve greatness like that. Achieving success requires sacrifices.
Edison is another example of a guy that would work really long hours. Look at everything that he accomplished. You want to be mediocre, work 40 hours. You want to be great like Edison, work your ass off. Don't listen to the little people that tell you not to work your ass off. That is the road to mediocrity.
Now, if you are saying that you want to have time for family and be another cog in the machine, 40 hours are great for you.
edit - OK, after further reflection I think that what the title means is that IF you are just a cog in the machine of a large corporation AND you are working long hours then something is terribly wrong. If that was the original intent then I completely agree. Is OK to do it once in a while but if it is normal then something is terribly wrong.
Now, for academics, athletics, other competitive fields and even startups at least in their earlier faces you still have to work long hours or the other guys will steam roll you. Eventually though you do hit a point of diminishing returns so you have to watch for that.
