I absolutely see your point, and the sense of entitlement you point out has, fairly or unfairly, been discussed at length, so I won't beat a dead horse. There's something to it (or we wouldn't be talking about it), but painting with such a broad brush based on personal experience is a dangerous logic game.

Youtube videos are not play. iPhone games are not play.

I've battled with this with my own daughter. Of course, I make her put down the screen and go outside and play on occasion, but games and videos are play. Its just a different kind of play than we're used to. The phenomenon will probably hold true, too: kids play at what they're interested in, so those kids who play at games and videos are likely to incorporate that interest in their chosen career, to a certain extent. I'm certainly not saying it's good for them, or that they don't need to put the screens down (I'm a huge proponent of that), but I don't want to say that kids need to play differently because they're not playing the way I did or want them to.
