Gay marriage has gained full legal recognition in the US, and some have speculated that polyamory may be next to receive the same treatment. According to the Merriam-Webster dictionary, polyamory is defined as
the state or practice of having more than one open romantic relationship at a time
while polygamy is defined as
marriage in which a spouse of either sex may have more than one mate at the same time
Currently, polygamy is outlawed federally and in all 50 states in the US. However, several cities in Massachusetts have passed local ordinances extending the benefits of domestic partnerships to those in polyamorous relationships.
Neuroscientist and fiction author Erik Hoel wrote the following about polyamory in the year 2050 in a blog post published August 25, 2021
Polyamory, the fastest growing cultural movement when it comes to novel forms of relationships, will continue to increase and become more open in the public eye and likely be legalized nation-wide by 2050.
