Artificial Intelligence Mention artificial intelligence, and many people may think of future wars between robots and humans. The advances of this technology, though fueling concerns about its potential pitfalls, are transforming human society in many respects. On one side are the positive changes that AI will bring. Setting human labor free from repetitive work, it has broad applications in both commercial and academic field. Internet giants could take advantages of this technique building detailed customer profiles that can be used to target advertisements or recommend items of interest. AI learning enables scientists to sort through reams of data generated from atom-smashers more efficiently to search for new subatomic particles. Look the other side, though, and there are plenty of potential pitfalls. As AI products proliferate, concerns have become more widespread. The immediate concern is that the scramble to amass the data needed to train AI systems is infringing on people's privacy. Tones of data concerning personal information from faces and health conditions to hobbies and friend zones are being processed and stored by apps or social media to form the so-called "Big Data", in many cases without any consent from the users. As AI systems start to be applied in areas like predictive policing, prison sentencing, job recruitment or credit scoring, the second area of concern is that of "algorithmic bias" - the worry that when systems are trained using historical data, they will learn and perpetuate the existing biases. Advances in AI often trigger worries about human obsolescence, but the good far outweighs the bad. What we believe is that machines will end up as assistants to biological brains rather than replacements for them, in the way that other technologies have done.
