Hi,

You write "The communication paths between engineers increase exponentially as the team grows in size.", but in fact the total number of communication paths between n nodes is equal to n * (n-1) / 2, which is not an exponential growth, but an polynomial growth (quadratic to be exact), i.e. O(n^2).

This allows me to delve deeper into some of mentioned concepts

Hi,

Thanks for the wonderful newsletter.

You have given a good overview on the type of technology stack used, it would have been much more helpful if you could have included about databases, and messaging queue being used.
