Yes. Any fledgling intelligence finds the low hanging fruit first. Right now its like a child, learning and repeating. Its the building on that intelligence that's impressive. In a general sense its slow because it has to do all fields simultaneously. Specialized the speed is much faster and in many cases already much further than human intellect.
Again your thinking like a human. AI is not human. If you dont want people to create evil you have to stop them. The fact that your concerned not because the AI is inherently but because people will corrupt it should tell you everything you need to know.
