Some examples that can easily push you beyond 64 GB: - high resolution photo editing: when you start with a 80 mpix / 48 bit photo from a medium format camera pushing beyond 16 GB requires only a couple layers and a couple undo steps being available - high resolution video processing. 1 second of uncompressed 4k 60fps video is almost 1.4GB - very large application compilation: building Android requires 16GB of RAM/swap - I'm sure there are apps that push that requirement even further - development environment for a complex system that requires you to run dozens of VMs if you want all components running locally (I've had to run 2 VMs with 12GB requirements each once)
