Is this inevitable, though? How many PMs and directors and ambitious engineers does Google Maps hire? If a company puts someone in a role, that person will do everything to make something happen, right? As for Google Maps, that means more and more features will show up on the maps.
Most of the products reach their inherent feature maturity (a toaster just needs to toast and eject) and beyond that much isn't needed by the end users (a digital temp display, Bluetooth connectivity with notifications to mobile app when toast is ready and such) but rather gets developed either:
Because Product manager has to show and prove his/her worth to the higher ups OR the backlog should be full and the team MUST NOT sit idle.
In my observation - some 60% of the written software comes from above and that ranks far higher than any critically necessary technical debt no matter what unless software comes to a grinding halt.
