What do y'all think? Given people get dulled by the same stimulus, what do we see as the future of dating?

Personally I think we will have short term contracts to create children and raise them to a certain age, after which parents will end marriage. Say a 10-12 year contract. Father takes the boys after they hit adolescence. Less dramatic way to build a family that is more in line with human psychology and desires. I think it's unrealistic to expect humans to be faithful to one person after 15+ years. And most open marriages fail.

What say you all?
