AI is overrated. Literally just a computer program, everything has to be programmed. It's even a stretch to call a computer program an "intelligence". There is no "self-learning", an application can be given data but it will only do what it's programmed to do with that data. Trading bots are not "artificial intelligence", they are simple programs that buy dips and sell peaks.

The most advanced AIs out there are used in video games and advertising. The traffic system in a virtual city like GTA is actually an incredibly complicated artificial intelligence, but it is just doing what it is programmed to do, detecting other cars and avoid collisions just like the self-driving AI. Targeted advertisements is probably the best example of an advanced AI, the system collects data and uses it as if it were a self-learning intelligence. But still, it's a computer program doing what it's programmed to do. The computer didn't decide on it's own to listen to your conversations, convert the audio to text, add that text to a huge secret profile for you and then scan through that data for brand names or product suggests to show you a related advertisement the next day... a human programmed it.

TLDR; AI isn't as scary as people make it out to be
