Year after year, improvements in AI have enabled us to perform more and more complex tasks.
These tasks impact every aspects of our lives, including work, home, and society as a whole. Some of these improvements relate to our understanding of the world, reasoning, and pattern matching. This is why we see smartphones getting smarter (e.g., Siri, autocompletion of messages, speech to text), as well as cars that are getting better at driving on their own (e.g., Tesla Motors Autopilot planning the best route home as well as handling the driving itself).
So in essence, AI makes your daily life easier by doing the repetitive and boring things so we can all focus on the more interesting parts, as well as uncovering a deeper understanding in human behavior to allow technology to work around and for us.
