...what? The majority of people access the Internet from their phone, and not only since yesterday either. Are you arguing that this is temporary fad somehow?
I am arguing that at some point there wont be any more people without phones, meaning it has reached critical mass and so IPv6 adoption will stall. The number of smartphones in the world will not keep on going up forever.
I don't think they are arguing for a decrease. I took flatline and peter out to mean stabilize.
