They've converged because manufacturers kowtow to the maximum likelihood sale, not because we think they're nice.

Of course, some people think they are nice. And yeah, maybe in a choice discrimination/maxDiff study, I would choose some of these converged styles over other styles, but not necessarily among all potential options.

Then, because manufacturing capacity is limited (whether we are manufacturing cars/spaces/aesthetics/ideas), the choice set that is actually available narrows.

Call it the tyranny of data science.
