[Avatar: TLA] Do you think the Avatars influence will dwindle over time?

If we take from real world examples, the growth of technology and the human population itself could start to overshadow the Avatar. Would they even need the avatar then? How would the avatar handle a world where nuclear weapons exist?

A world where nuclear weapons exist will either use them, and end, or not, and not. They're a null factor when it comes to the Avatar, and the main effect they'd *have* on the Avatar is giving them something else to worry about. 

The thing with the Avatar is, as long as people respect and believe in them, there is no reason *any* amount of technological advancement could ever outpace them. Because their power to bend all four elements is just... a neat bonus, on top of the *true* strength of the Avatar. 

Their spirit. 

Not Rava, though that helps, but each Avatar themselves has, by definition, the soul of a hero. Each one will do their best for the world. And as long as people are willing to stand behind that, technology may change the *scope* of the world, but never the Avatar's influence on it. 

Add to that the literal magic that technology will never be able to meaningfully replicate, and you've got a being that will not dwindle as humanity grows, but grow right alongside it.
