The article presents the authors’ conceptual vision of a new stage in the development of law as a social regulator, a stage that is predetermined by the biotechnologization of human activity. The purpose of the study is to articulate the foundational vectors of potential transformations of law—both at the doctrinal level and within the sphere of legal implementation—under the influence of two constitutive factors of the contemporary context: biotechnology and artificial intelligence. Proceeding from the premise that the emerging reality substantively reshapes a number of elements traditionally regarded as axiomatic within legal theory, the authors outline possible trajectories for the further development of law under conditions of biotechnologization. Particular attention is paid to the methodological grounds of such transformation, which are determined, inter alia, by changes in the very nature of the human being, the modification of fundamental legal conceptual and categorical units, as well as shifts in the content of legal relations associated with the emergence of novel features of subject–object interactions. Each identified methodological ground necessitates the revision of existing doctrinal and regulatory approaches, which allows biotechnologization to be conceptualized as a new point of legal development in the current socio-technological environment. This conclusion is supported by emerging trends in normative regulation, demonstrated through the authors’ analysis of BRICS countries, namely the Russian Federation, the Federative Republic of Brazil, the People’s Republic of China, and India.
