The funny thing about this list is that a few of the items, while intended as satire, are actually spot-on. Especially item #1: "But the rate of source code commits continues to grow proportionally with the number of engineers. This is in clear violation of the law that Fred Brooks established nearly 40 years ago in The Mythical Man Month." Whoop de do. This might, just maybe, because no particular behavior of FB rea…
It's likely that the code is not coupled. Fred Brooks studied OS/360, which was essentially one big component. Facebook is, presumably, many separate components that don't depend on each other in any way, and so the "teams" are much smaller than "all of Facebook". If you watch velocity on individual components, you'll probably see sub-linear scaling as Brooks predicts.
How could that even be possible?
