Again an article painting an idealized picture of the past that never existed.
It's a velocity + availability "no Tom Brokaw" argument as applied to relationships. Like the question it's poking at "if an ecosystem can radicalize a person, what are its effects on a relationship?" is at least interesting to consider.
I do think that's a good question to ponder and one I hope I'm thoughtful enough to consider in my future relationships. If it were my idea I would keep growing it into something, but that's just me.
