    So on the one hand it's nice to see when a cool algorithm or framework is used IRL.

    On the other hand, actually applying a 'stable marriage algorithm' to people makes a bunch of assumptions which are worth interrogating:

    - Do people actually know what they want even in the short term?

    - Do people's preference change meaningfully over longer periods of time?

    - Does your preference _upon reading people's profiles_ have any strong relationship to your preference after spending any amount of time with them?

    The property that right after being matched, no one could have matched with someone whose profile they preferred more does not mean that this will create stable relationships.

      I don’t think you are legally bound to marry. And if it stops working, divorce before resentment.
