Not to be flippant, that sounds like working at a lot of big tech companies nowadays. More conceptually, you have the constant churn of in house tooling meaning what you wrote last year needs to be rewritten to work with the new version of X (be it the ticketing system or the new process to store secrets or the new frontend framework that will fix everything). And even more concretely, there are teams that will fully get sunset when a new product or service deprecates them or beats them to market. Famously, that was how the iPhone was developed, with teams competing internally in Apple. https://9to5mac.com/2017/06/28/iphone-creation-click-wheel-t...
