Divorce as a service. We already have marriage as a service in the form of “open relationships” one can argue. How about child bearing as a service? Perhaps in the form of surrogate or finding willing donors/carriers? And then child care as a service under the umbrella of adoption as a service, child rearing/daycare as a service (for example an app that allows each party to sign up when and how they would split the time spent with the children.

I think this model in western society has a long way to go in each of the above areas open for disruption some form or other.
