The history of Artificial Intelligence is long, but it's only been recently that technology companies and markets have begun to get excited about it… Why? After a few decades of exploration of symbolic AI methods, the field shifted toward statistical approaches, that have as of late started working in a broad array of tasks due to the explosion of data and computing power, this in turn has led to machine learning and, most importantly, enabled deep learning. This is great news for the tech industry. The downside is that there aren't enough data scientists that understand deep learning. For those who do, there is a huge demand for their services.
