IMO, when you see car companies 2020 model gets 3 more horsepower or 1 more MPG, it’s better to consider how difficult that was rather than simply expecting it. Even a slightly better toothbrush is a positive life change. We have normalized progress, but even seemingly incremental progress is making the world a better place.

Further, it can take revolutionary change to maintain incremental improvements. Filling HDD with say Helium has a lot of knock on effects hidden by the spec sheet.
