It's diminishing returns.

At a certain point there's just no point in jamming in more hardware or making a device smaller.

Back in the day every year brought huge advancements and new features, but we really need to just chill on annual models by now. Let refreshes happen when there's enough advancement to justify it. Especially for more expensive stuff like cars.

Currently there's a shit ton of "last year(s) models" all over the country that were built and never sold. But every year a "new model" that's slightly changed rolls out to justify a higher price.

They'd save a shit ton of money switching to a five year refresh, and all those "new old model" cars would still just be "new" and sell at the same price as one that just came off an assembly line.

But then automakers would lose that dwindling customerbase who buy new every year to have "newest".

Anyways, the point of all that is I don't stay up to date on changes. When I need something, I jump back in and virtually always end up picking something that already has a new model out. The premium for best/newest is just never a good idea.

We're at the point we're very few people ever get close to utilizing it anyways.
