Its going to be half human half robots they will be thire own race

I think humans will always be the leaders. At least for a the next 600 years. I understand that AI is more powerful and intelligent but we can't just say that there is a more sustainable condition for AI to perform in more than 4 countries. The majority of the Earth's population cherish their tradition than technology but we can not see it because we are too busy watching the western entertainment industry.

If you saw the movie "Ex Machina" you would definitely think robots would take over But I don't think that's in the near future.

maybe robots but that's probably many years later. it would feel odd if robots become our leader.
