The evidence suggests it does. How much of this belief do you base on your ideals and how much is based on reality?
There used to be just game buttons (joystick + one button on Atari, for ex). There there were start and select. Then there was a console-specific power button (the "XBox" button and the "PS3" button on the Xbox controller and DS3 respectively). Now there's a share button. I dunno dude, it looks like the arrow of history is actually pointing the opposite direction from what you said in this comment.
The Xbox button and PS buttons are not "specific" since they have several functions - they pop up a menu where you can access a long list of functions. Having a single button for sharing to your network is borderline stupid, since it will flood the social networks with useless crap nobody cares about.
Game streaming is popular because of the personalities and explanations. Without narration, the vast majority of videogame clips are just cold and sterile, and not at all 'social'.
"Look at this cool thing I did" is the go-to example in this kind of demo, but in reality nobody cares. We want a human voice.
Power buttons are somewhat special just from a hardware point of view; I don't think they are especially useful for this question.
You can't navigate a menu to reach a power-on function. A competing power button service will never come out to replace the currently popular power button service. Every single Xbox or PS3 owner will use the power button(s) with regularity.
He's referring to the center button on PS3 and XBOX controllers that goes to the xbox dashboard or PS3 dashboard, or the home button on the Wiimote, etc... at least, that's what I assumed. That button does count.
Sure it does. So many things happen in cycles. Contiuums are really the trace of a penduluum.
We may still be swinging toward "programmable" buttons, but trust me, things will start swinging back at some point, though perhaps not for the reasons we might think.
