It is a gargantuan task to compile a handbook on artificial intelligence (AI) that focuses on global perspectives of law and ethics. This is not only because new developments in AI are constantly reshaping understandings about what might be possible, but also because the approach to law and AI differs so significantly across jurisdictions. These jurisdictional differences have resulted in a wealth of ever-expanding literature and regulatory material that requires thoughtful analysis. Analysing this material, contemplating the ‘known unknowns’ and the ‘unknown unknowns’, becomes even more difficult when academics have differing approaches to AI evaluation. On the one hand, many, often with a European frame of reference, are very focused (if not obsessed) with regulatory measures, while others, often with a common law background, consider AI from the perspective of longstanding legal principles.
