bitcoin is maintained by core developers, would Bitcoin die a natural death if the developers no longer exist? Or if they stop maintaining/developing/upgrading the system?
bitcoin is not a physical machine to age as it works and need "maintaining"! it can continue to work as it is for may years without any issues. all the things you see are "additions" and although they have helped bitcoin's future but none of them were necessary for its survival.
besides, did you think there are only a handful of programmers in the world?
oh, and by the way stop centralizing bitcoin
