Great explanation, especially the way the example shows how quickly things break once real usage increases. One thing I find interesting is how different apps handle that jump from small to real scale. A lot of it only becomes visible once people actually start using the product, not during initial development. I have been browsing a lot of these kinds of apps on [https://unstore.io](https://unstore.io/) and it is interesting to see how different projects deal with scaling challenges in practice.
