I am afraid also. I read several articles this week about reaching singularity and how scientists are studying how to limit an AI's ability. It's pretty bleak. Eventually, AI will hit singularity and then we are not in control. Anyone who has read too much sci -fi as a kid (as I did) knows how this ends! There is a slight chance that AI might make some things better...but it may also decide we are the problem. Good article.
