2017 was an influential year for artificial intelligence (人工智能), not just in terms of the advancement of the technology itself, but also for the development of our understanding of AI's impact on our society.

When we talk about AI, often we focus on the belief that it is going to take away certain types of jobs. However, we often ignore the fact that this technology will also slowly spread into most of our lives.
Thanks to the development of AI, we are on the highway of IA, (human) intelligence augmentation (增强). Despite the great steps we've made in AI development and will continue to make in 2018, we are still years away from AI fully replacing human jobs. However, we are much closer to seeing the impact of AI spread into almost every job and the growth in human intelligence.
Take a doctor for example: AI will soon be able to detect and diagnose common diseases more quickly and accurately than humans. Now, doctors can spend more of their time explaining the possible diagnoses, communicating with patients and developing unique, reliable treatment plans that are most effective for each specific patient.
However, AI is so powerful and its adoption will only accelerate as it begins to help our work and allow us to focus on the parts of our job that are most important. But part of why AI is so attractive is also why it's so dangerous. That is, that same power allows AI that are making incorrect decisions to do so with greater speed and impact than humans have ever had.
This is why, as AI becomes more useful in 2018, it will also become more closely examined. 2018 will be the year when companies purchasing AI products don't just ask about the power of AI—they will make sure that it is tested carefully in advance, minimizing their potential unexpected impact.
