Outside say video and image editing and maybe lossless audio. Why is this much ram even needed in most use cases? And I mean actually thinking about using it. Computer code unless you are actually doing whole Linux kernel, is just text. So lot of projects probably would fit in cache. Maybe software companies should be billed for user's resources too...
I have multiple apps using 300 GB+ PostgreSQL databases. For some queries, high RAM is required. I enable symmetrical NVMe swaps, too. Average Joe with gaming needs wouldn't need more than 64 GB for a long time. But for the database, as the data grows, RAM requirements also grow. I doubt my situation is relatable to many.
