that still scales linearly with number of people, not quadratically.

  It scales super exponentially since each person is a member of an arbitrary number of groups and their actions have some non zero impact on each other member of the groups they are a member of, and each individual in each group with a member of which they have interacted with.

    if that were the case, numerical weather prediction wouldn't work. you can add up the impact for each neighbour.

      Humans are not mindless molecules whose only interactions are with the people right next to them.

        You're allowed to move the numbers that represent the people in the matrix multiplication such that the interactions are close by.
