I don't understand how Tinder is the example of that.

If I have time to meet a woman tonight and it's 4pm, what exactly is Tinder replacing? The hell of cold-approaching women at bars until one of them seems to like me? Mine my depleted social circle for a date? Wank off in my bedroom because I don't have any new prospects and be happy with that?

The whole point of Tinder is to find new face to face interactions.
