It's an interesting direction we're headed if polygamy is "next." What's after polygamy? We have to ask ourselves what marriage actually is. Approximate modern progression (discounting ancient marriages involving young children, which I doubt will happen again in the future): -A man and woman of the same race. Divorce uncommon. -A man and woman of any race. Divorce uncommon. -A man and woman of any race. Divorce common. -Any two people. Divorce common. -Any number of people. Divorce common. -Human and AI? Human and animal? Human and inanimate object? Who knows? Or does the expanding definition end with polygamy? I doubt it. This is not a slippery slope argument I'm making, it's a question of logical progression. Perhaps in the future marriage will be thought of as "a likely temporary agreement involving at least two beings - at least one of whom is sentient - for the purpose of convenience, love, and tax benefits."
