Does Machine Learning allow opposites to attract?

In 1958, the Monotones asked, "Who Wrote the Book of Love?". If we fast forward 58 years to the present day, would the'Algorithm of Love' be a more accurate title? It is certainly a valid question; such is the popularity of the modern online dating website. Users can forego the inevitable awkwardness of blind or speed dating altogether, having found out every last detail about their date before they ever have to meet them in person. Most dating websites utilise some form of collaborative filtering or a'Netflix style' recommendation algorithm that matches people with their potential partners based on shared interests and hobbies or mutual likes and dislikes.
