Some jobs had been changes and some of workers dissapeared from factories and they were replaced by Artificial Intelligence or robots. When the AI will be fully developed (or, at least, it will be compared with the human intelligence) they will replace many other jobs and some people are already asking if they will stop writing on blogs or if they will stop developing programms because of Artificial Intelligence. That may happen in the medium distant future, something that's more than 10 years and may close to 20 years, because Artificial Intelligence is still under development and there is much work needed for it (that's why some people are saying that AI revolution is rotten to the core even if it has good results).
Even if we don't know for sure which is the AI future we can't tell that the Artificial Intelligence must not control the nuclear weapons. We don't need their mistakes in that field and we sure don't need Skynet using that nuclear weapons outside a Terminator movie. The entire world may go boom even becuase one mistake and nobody wants it.
