  This paper analyzes the evolution of control systems for astronomical telescopes. For this comparison we look through the lens of three world class telescopes: Gemini, GTC and GMT. The first two have been in operations for twenty and ten years respectively, whilst the latter is currently under construction. With a planned lifetime of 50+ years, obsolescence management is a common issue among these facilities. For the telescopes currently under operation, their real-time distributed control systems were engineered using state-of-the-art software and hardware available at the time of their design and construction. GMT and newer telescopes are no different in this regard, but are aiming to capitalize on the experiences of the previous generations so they can be better prepared to support their operations. We highlight the differences and common aspects of their software and hardware infrastructure (operating systems, middleware, user interfaces), the pros and cons of each choice and what has been done and what is being planned for obsolescence management.
