What does this mean for "opposites attract" and "my better half"? Many substantial, long-term, fulfilling relationships are mutual partnerships where each person grows and as a couple find things that are "theirs" while filling critical roles for each other.

Fine-grained matches might not be that great. What will one have to learn from a relationship? What new interests will be developed? I know that FB's sociologists and ML experts have been considering these aspects more than I, but I fear the continued segregation and viewpoint-reinforcement that FB and algorithmic association sites subtly (or invisibly) are forcing upon society.

One would hope that they've come up with a couple different algorithms, to find matches that fit those different scenarios. "Here's some people who compliment you well. Here are some people that are different. Here's someone who's basically you."

i dont believe they will be optimizing against "who X matches exactly with Y", but against what matches ended up successful.
