Artificial Intelligence seems like a double-edged sword. As of now, there's a lack of jobs, resulting in unemployment rates across the world. If we are to create artificial intelligence, it can greatly contribute to the lack of jobs and raise the unemployment rate.
Beyond that, however, AI is an extremely cool push in the technological future of the world. It can basically be used for anything that requires computation. They'd be very good at data analytics, graphing profits, managing funds, and essentially most of what humans already do.
This isn't an issue, any technological advancement will be good for the human race in the long term. Short term it may make some people in certain employment sectors unemployed but it will increase global productivity and can lead to many more employment opportunities. The danger does not come in terms of increasing productivity but how things are then managed. It's easy to see that better technology leads to more resources for the world, the issue is then as to how to fairly distribute these. If the rich and powerful have a monopoly on technology and the resources it helps to produce then we can end up with a situation where the rich/poor divide is only heightening with time.
