I have a swap partition in my current system (64GB), I’ve had one on my previous system (which was 11 years old, with 16 GB) - I have seen my system¹ swap at most 5 times, and every time it was software misbehaving so badly that it made the system unusable.

I know this is anecdotal evidence - but my experience is that it’s getting less and less relevant for most desktop systems.

Edit: ¹my old system, the new one has not swapped at all in the past year.
