Mentioned in the article, but deserving of more time, is that games are a symptom of this attitude, not the cause. For a lot of reasons, society in general seems to have basically just stopped trying. Difficulty is no longer a challenge to surmount, but an excuse to just walk away. I see it every day in otherwise hugely intelligent students (soon to be in the medical professions no less!) who just outright refuse to learn new things. Better to just have someone else do it for them. Why? Well maybe, as suggested here, that it's a fear of failure. "I might not do it right, so I'll just let the expert do it instead." This snowballs until I have graduate students and medical residents who won't even learn (not don't know, but won't learn) how to reboot a computer. (Yes, true story. Happened last week.)
In games, this is reflected by a removal of failure, even any negativity at all. Instead, "difficulty" is limited to over-the-top celebrations of the concept like I Wanna Be the Guy. That doesn't help anyone.
