AI is being touted as the biggest disruptor of legal services in living memory. Claims that "100,000 legal roles are to become automated", and "robots will replace lawyers in the next 20-30 years" mean that the trend cannot be ignored. In December 2016, ARK's best-selling Robots in Law - a vendor neutral primer on what artificial intelligence could do in legal services was published. This was written as a snapshot of how things stood at that point in time. It was early days for AI in legal, so it wasn't about implementation or adoption but about technological developments and possible uses. A year later, this book focuses on how firms have begun to adopt and use AI, providing detailed insight into the different practice areas or functions that AI has been used to drive efficiencies. The book is designed to help law firms learn lessons from previous implementations and consider which technology would be right for them to adopt.
