Never is such a harsh word. I used to work at an x86 CPU manufacturer. We had large memory requirements on x86. There was a time when you couldn't fill an x86 system with more than 128GB of memory. In those times, we occasionally had to use swap as additional memory for processes that grew larger than 128GB. Yes, it was slow. Yes, it sucked. Yes, we still did it. And sometimes, we even stuck swap on a 32GB RamSAN just to make the performance suck a little less. The point is not all use-cases can be simply solved by physically adding more RAM to a system or by mmaping. Sometimes there are physical limitations that prevent you from waving the magic wand. Sometimes, you just make do.
