On one hand you could say he is bored, bitter, "old" dude who is tired from keeping up with the advancements and declares the end of progress.
On the other hand, you could argue that there is some genuine insight there. Internet is not an internal part of being a human. I even subscribe to the idea that it many ways it goes against being a human (social and physical detachment, desensitized emotions). And in the end of the day, no matter what is said and done on the internet, our existence is primarily physical.
Maybe the internet will not die, but maybe there is a regression to the mean. It feels like the excitement of the "digital self" is past its peak and people are slowly re-discovering that offline life is "cool again". Or if not "cool" a necessary plane to exist in order to effect changes. I think the Floyd example was on point; change happens on the street, not online. The stakes are simply not high enough there.
