what in photo (or video?) editing would ever take up 128GB of RAM? Not trolling, really curious. I can't quite imagine PS working faster with that much RAM, I doubt it would use it?
For photo and video, probably nothing... Even in after effects with 4K video and layers you'll be hard pressed to exceed 16GB, unless you extend the frame preview range so that you can scrub through more of the video at a time.
You do take a hit once you start running development tools, programmers often run virtual machines, IDEs and other diagnostic tools simultaneously and each one takes a nice chunk out of the system RAM. Once you have a dozen of them running and each one needs a few GB then you have a problem.
Another possible application is anything that deals with reading/writing large data sets like a server or ZFS-based NAS, but that's a whole other subject and you'd need ECC RAM for that anyway.
Of course, as Cyber said, you can also set up a RAM disk and use a chunk of RAM as ultra-fast local storage, although the volatile nature of RAM means that if you lose power then all the data will be lost. Probably not too big of a problem if you use it as scratch space, unless the scratch is also used as the crash recovery directory, in which case a BSOD would ruin your day more than usual.
RAM is never a bottleneck unless there isn't enough of it, and 16GB is easily enough for even the most memory-intensive tasks a typical PC user can muster. The speed of RAM is still increasing with some companies having now developed DDR4 4266 modules, but honestly it's so fast even at the base 2133 speed you'll be hard pressed to tell the difference, even in things like 7-zip which are heavily RAM-dependent.
When anyone asks, I usually reccomend the cheapest set of 8 or 16GB modules they can find a good deal for, anything else is usually a waste of money.
