Software is a gas, it expands to use all available resources.
I have 32GB of RAM, and run out occasionally. At the moment I have two CAD programs, thousands of pages of datasheets and reference manuals, an IDE, and ~50 browser tabs open. I don’t HAVE to have them all open at once, but it does save me a lot of time.
My next machine will have 128GB, and I expect that will run out of memory too.
Also, sometimes you need to use software that has a memory leak, so a bit of extra RAM gives you some more time before it crashes.
Photogrammetry can also get resource hungry.
The best season is the short window in spring where it’s warm out but the bugs aren’t out yet.
