Machine learning can potentially change the world and in terms of intelligence this self learning systems can take over human intelligence. This TED Talk explains the true potential of Machine learning.
Deep learning a form of Machine Learning is growing exponentially. Which means that not only the the machines are learning fast, but they are learning faster and faster. As you can see in the graph shown in the video, deep learning systems are only 5 years aways from equalling human intelligence.
The improvement in machine learning implies that we will have more intelligent computers and intelligent robots in the future. There will be a time when robots are going to make more robots that will constantly keep improving itself. It is practically possible that we will have implants that will make us humanoids. Half humans half robots.
