I truly hate, more than anything else in the tech discourse, that this gets trotted out every time the discussion of RAM comes up. "unUsED rAM iS wASTED RAm", always used to defend and justify abhorrent and incompetent software development practices. Even with 32gb, I routinely run into out-of-memory crashes on a near-daily basis with workloads that should not in principle be anywhere near that usage.

If they were making decisions based on RAM, they were almost certainly encountering real-world issues which prompted looking at their usage statistics in the first place, rather than just looking up their RAM usage metrics for funsies.
