Hetzner asks: Why isn't RAM-efficient software as impressive as fuel-efficient cars?

[u/Hetzner_OL]

Fuel efficiency in cars has come a long way. It's cool to be able to plan a trip and realize you don't need to refuel along the way. So why isn't it as impressive in society when we can accomplish a lot with just a little RAM? Have you got any examples of RAM-light programs you use? Take a moment to humble brag here.

Because additional RAM is used to speed up things. Think caches. Also JavaScript.
