It has long been the development of artificial intelligence. We've all seen the movie "Terminator" and we know where it may lead. On the other hand for a person is very attractive to shift all the work to robots. You for which option?
Firstly, I think that this thread should have been created in the "Off-Topic" section, not at "politics & society" because it is still a science-fiction mostly, we dont have real artifical intelligence in use, there are only different kinds of prototypes made on particular scientific projects.
Same as @Scott J, I dont think we need to take AI as something dangerous, which we should never research and implement anywhere.
Indeed, it might be something lethal at some point when technology will go years forward, but we can see just too many branches of industry where AI would make a huge difference to ignore that issue.
Films like "Terminator" is just a science-fiction, dont forget about that.
