China goes under the microscope in this week's episode of Smart Dust. When we talk about innovation we often immediately turn to the US and the UK – overlooking the second largest economy in the world. So, this week we discuss the hottest topics in China's technology industry - and as the world's leader in Artificial Intelligence, there is a lot happening. Namely, China's new social credit system putting a score on its citizens – is it constructive, or just plain scary? Can we digitise morality? We also examine three exciting Chinese start-ups and have a look at how China is putting the fun back in social media.
