In general I have much better experiences on MacOS with 8G of RAM than on Windows or Linux. Very happy that I have 16G on my current machine, but I feel like 90% of the stuff I do (even as a dev!) would go perfectly fine on 8G.

I feel like people are using their experience with 8GB on other platforms and projecting their experience to other people. I feel like MacOS memory management is VERY on-point.
