Indeed, there's more than one branch of democracy - We are used to representative democracy but there's other types like direct, semi-direct, centralized, corporatist, etc - Not to mention that in theory ideologies like fascism considered themselves partially democratic because of the representation ingrained in corporations, so it becomes complicated to define democracy. I think some kind of democracy, even if it's just for the elite, will always exist because we need people to voice positions, but I'm not confident that throughout our history and existence we will always use the system of representative democracy - I'm just trying to think ahead of time - And perhaps in the future humans will look at representative democracy with a skeptical mind while technocracy and robotics reigns.
