When done well, swap can be pretty useful. I have a Fall 2019 MacBook Pro maxed out on CPU (8 cores) and RAM (64 GB) - MacOS still regularly compresses (highest I've seen so far: 12 GB) and/or swaps (highest I've seen so far: 16 GB) relatively unused memory to make more space for other applications and hot caches (which are still useful even with an PCIe SSD).

Keep in mind that everything feels fully snappy and responsive while this is all happening.
