On-topic, I think its a natural evolution for organizations to stagnate and calcify unless there is a fundamental recreation. Lots of things could be cherry-picked here for anecdata (Roman Republic, Roman Empire, General Electric, <insert fortune 100 company here>)
I don't think that's bad. You wouldn't want an innovative person being your line cook at a restaurant -- you want the innovative person to be the chef. We also don't want the laws governing the countries we live in to violently change. Systemic, evolutionary, progress is good.
The challenge is figuring out a balance and what to do to prevent the organization from calcifying (becoming product lines on life support), prevent it from throwing away what makes the organization good (chasing the next big thing), and continue to let the organization innovate and thrive (stay relevant) without being eaten.
