Fascinating, and certainly getting hotter in the job market as we speak. This technology will permeate just about every aspect of our lives, and represents an incredibly wide swath of applications. And getting wider by the minute. That being said, AI itself is a branch of mathematics. As such, you would be well-advised to get into a mathematics curriculum. AI is also obviously closely coupled with computer science and engineering from a practical standpoint. I mention that because you could easily stick to theoretical AI instead of AI applications, but my person prejudice is seeing robots and other machines do cool stuff that makes them seem human. I kid you not. The way classical robotics worked for a long time was that folks would program robots with algorithms that they hoped would allow a machine to interact with the real world the way people do. But that's not how people generally work. There are algorithms in us, to be sure, but we learn all the really complicated stuff by seeing examples, failing, trying something else, getting advice, trying again, etc.. Think about how difficult it would be to teach a baby how to walk by giving it a list of rules to follow and then having to add to those rules every time the kid bumps into something new or tries to walk on a slippery sidewalk instead of a carpet, and so on. So what AI does is take advantage of what we call "Big Data", which is, quite non-mysteriously, just lots and lots of data. And our Internet of Things that hooks all of the stuff in the world to each other over the internet provides tons and tons of data. So if you want to think about how many applications there might be in the world for "lots of information" being used to do "whatever the heck you want", and you think that might be a really, really big set of stuff.... yeah. So there's pretty much nothing in the world that won't be related in some way to AI. And if you want to get into it, you've got the future on a leash!
