We'll still have swap as long as CPUs support virtual memory. Nothing beats using a dumb programming language and process model, and without explicitly deciding anything, being able to scale past physical memory until your working set just barely fits. Further, there may be some performance benefit to swapping idle process memory to make room for more buffer cache. It's true that for interactive use (especially a laptop with spun-down drives), you may be happy without swap. But I don't see the facility being mothballed.
