His point is that the long-distance connection has been digital for many decades now, even back in the 1980s according to one comment here.

He's being hyperbolic of course, since there's people in their 90s and 100s who made phone calls way back when you had to talk to the operator to place a long-distance call. But the general point is valid: how many people here actually remember the days when the connection was all-analog? You would have had to be making LD calls in the 1970s probably.
