Time magazine recently featured an article that asked, "Is monogamy over?" The article offered various opinions, including "monogamy is a charade" that leads to "institutionalizing dishonesty," and "[monogamy] is just an option, not the default," and "There's no right, there's no wrong." Time also featured Pastor Andy Stanley who offered this biblical view:

Monogamy is more like an endangered species. Rare. Valuable. Something to be fed and protected. Perhaps an armed guard should be assigned to every monogamous couple to ward off poachers. Perhaps not.

The value a culture places on monogamy determines the welfare of its women and children. Women and children do not fare well in societies that embrace polygamy or promiscuity. In the majority of cases, sexual freedom undermines the financial freedom of women. Sexual freedom eventually undermines the financial and emotional security of children.

If we are only biology, none of the above really matters … If we are only biology, monogamy was probably a flawed concept from the start. But very few of us live as if we are only biology … As a pastor, I've officiated my share of weddings and I've done my share of premarital counseling. I always ask couples why they are getting married. Survival of the species never makes the list.

The "I" and "You" that inhabit our bodies desire more than another body. We desire intimacy—to know and to be fully known without fear. Intimacy is fragile. Intimacy is powerful. Intimacy is fueled by exclusivity. So, no, monogamy is not obsolete. It's endangered.
