I have 32GB of RAM and it sits unused most of the time. Right now I am at 4GB/32GB. It simply isn't a significant source of memory consumption. Open Atom and you can easily get to 500MB for a single application, which is completely wasteful. That browser can run dozens of apps in 4GB.
On the other hand, my browser (Firefox) keeps overflow through 8GB ram few times a day. Sometimes I wish people programmed like we had 512megs in a luxury machines.
I also have 32 GB RAM and right now am at 25 GB + 2.4 GB in swap. I'm at around 20 GB most of the time but always have at least 3 Firefox tabs open. Sometimes a buggy process (looking at you, Apple…) decides to go haywire and use 30-60 GB of virtual memory. I don't even notice that until I have a look into the activity monitor. Handling RAM spikes seems to be no issue at least on macOS.
