The tyranny of the marginal user is about regression to the mean.

If you haven't read the original piece from my friend Ivan, you should, it's excellent: https://nothinghuman.substack.com/p/the-tyranny-of-the-marginal-user

The marginal user represents the gradient towards the most bland thing.

If you chase that gradient, you will speed along the gradient towards the most bland, mundane, same-y thing.

The maximal regression towards the mean.

You arrive at the local minima of the basin of the given domain.

A gravity well for all use cases that start anywhere in that basin.

E.g. all dating apps regress to a smartphone-optimized experience that emphasizes swiping through pictures to find superficial matches.

E.g. all smartphones regress to a 6.7" slab with 3 cameras on the back, 2 on the front, a day of battery life.
