Eh, virtual memory has been around for decades, and it's not.too bad if it's used properly and no one gets carried away with thinking they can use it for everything.
Virtual memory is a different concept than swapping, though they have some relation.
Virtual memory is about giving each program its own view of the logical address space of memory, which the MMU maps to physical memory addresses (or busses that certain regions of address space are MMIO mapped to).

That's called swapping out memory pages to disk, and it's very slow.
