To be clear, I don't blame the poster of this comment at all for the content of their post – this is accepted as "common knowledge" by a lot of Linux sysadmins and is probably one of the most likely things that you will hear from one if you ask them to talk about swap. It is unfortunately also, however, a misunderstanding of the purpose and use of swap, especially on modern systems.

Except for sometimes when it is beneficial to store tmpfs files on RAM for speed or saving your SSD some unnecessary writes.

https://wiki.archlinux.org/title/Firefox/Profile_on_RAM is a good example.

    I think people are a bit overly afraid of SSD lifespan. I've been using my SSD heavily for like 5 years, and it's a QLC drive which everyone told me would die very easily. Turns out it's still only used like 10% of its writes
