>As another point of comparison, a 2013 iPhone 5c (technically not released until the last quarter of 2013, but we're being generous here) had 1GB of RAM and 8GB of storage, though you could upgrade that to 32GB. A modern iPhone has 6GB of RAM
Fine, take that as your reference. It still shows that growth in memory was 1000% faster not too long ago.
No, it doesn't. It shows that Apple's RAM offerings have grown at widely different rates depending on their product. Apple has been stingy on memory compared to the broader industry. The biggest EC2 instance you could get in 2013 had 244GB of memory, but today you can get one with over 24TB of memory.
...and that still proves nothing about the growth of RAM usage in that time period, because the size of the offerings in individual products are largely independent of the increases in RAM usage.
