"Gen Z buying iPods and people buying N64 games again is not evidence of the monoculture breaking apart - it's a retreat into the past for the enlightened few because their needs are not being met by modern goods and services."

That seems like a charitable interpretation to me. Maybe it's just a retro fashion trend that is even at its peak a tiny blip in the market, like back in the 90s when bell bottoms were "in". Give it a few years and we'll see.

The iPod and N64 are about 20 (or more, for the N64) years back from now, no? So about as far back as bell bottoms were from the 90s.
