Max Brenner, as in Chocolate by the Bald Man in NYC?
I think the form of conversation is changing, but it's not dying. My friend and I have debates and arguments about things all the time.
In addition, like James, visiting family or friends used to be about watching stuff together. Nowadays, it's when we do the opposite: maybe talk about shows, or catch up with each other's lives.
I think it's better to look as conversation and lifestyles changing rather than dying.
