What an absurd statement.

Do you use a laptop? I do and I'm using swap space right now. I would like to buy a laptop with 32 or 64 Gigs of RAM but I can't as most(all?) laptop makers don't ship with a memory controller that permits more than 16 Gigs of RAM. And I can afford to buy more RAM.

What is the rule for setting swap size, or can I use just swap file just like on win/mac? (I heard it will disable hibernation then)

The basic rule is `RAM + 2GB`

I usually peak at 34GB, unless I have reason (like needing/wanting to enable full hibernation) to use 66GB, 130GB, etc.

what if if you increase your RAM after installing the system?

It's a circular argument that people get into because they have the incorrect kernel settings. Even if you have 4TB of ram, someone will say to add more memory on disk. It just means the system is not configured correctly. I have 30k servers and not a single one of them has swap.

Physical? VM? Cloud?

I've never seen an environment with more than a couple carefully-tuned machines that didn't run swap on every last one

30k physical servers. 512GB to 1TB ram each.
