Yeah the justification I gave is pure theory until you're talking large distributed systems... and the theory amuses me here so I'm going to keep talking about it first.

But it's actually a place where practice happens, by coincidence, to match theory pretty well: https://www.ilikebigbits.com/2014_04_21_myth_of_ram_1.html

That's an interesting correlation between the sizes and latencies for cache levels. Thanks for linking it.

Though once you're at the "distributed" tier, I wouldn't expect further increases to be sqrt. Distributed within a datacenter is probably going to have a log(n) topology of links, and distributed across datacenters is a fixed number of milliseconds based on the area you're serving with no real connection to amount of RAM.
