Dating apps, much like social networking apps like Facebook, reduce our interactions to the shallowest form possible. So it is much better for people to not use these forms and resort to more laborious methods of interaction because these also allow a deeper more honest connection between people. Deeper and more honest connections lead to better understanding and appreciation of each other, which is good for society. Unfortunately we haven't even figured out how to ween people off easy "social interaction" yet, much less dating apps.
