Irresponsible Counselors: Large Language Models and the Loneliness of Modern Humans

Large language models (LLMs) have rapidly shifted from peripheral assistive tools to constant companions in everyday and even high stakes human decision making. Many users now consult these models about health, intimate relationships, finance, education, and identity, because LLMs are, in practice, multi domain, inexpensive, always available, and seemingly nonjudgmental. At the same time, from a technical perspective these models rely on transformer architectures, exhibit highly unpredictable behavior in detail, and are fundamentally stateless; conceptually, they lack any real subjectivity, intention, or responsibility. This article argues that the combination of this technical architecture with the social position of LLMs as multis pecialist counselors in an age of human loneliness produces a new kind of advisory intimacy without a subject. In this new relation, model outputs are experienced as if they contained deep understanding, neutrality, emotional support, and user level control, while at the deeper level there is no human agent who is straightforwardly responsible or answerable. By reviewing dominant strands of AI ethics critique, we show that focusing only on developer liability, data bias, or emotional attachment to chatbots is insufficient to capture this configuration. We then explore the ethical and political implications of this advisory intimacy without a subject for policy-making, for justice in access to counseling, and for how we understand loneliness in the contemporary world.

Mahiru: a federated, policy-driven data processing and exchange system

Secure, privacy-preserving sharing of scientific or business data is currently a popular topic for research and development, both in academia and outside of it. Systems have been proposed for sharing individual facts about individuals and sharing entire data sets, for sharing data through trusted third parties, for obfuscating sensitive data by anonymisation and homomorphic encryption, for distributed processing as in federated machine learning and secure multiparty computation, and for trading data access or ownership. However, these systems typically support only one of these solutions, while organisations often have a variety of data and use cases for which different solutions are appropriate. If a single system could be built that is flexible enough to support a variety of solutions, then administration would be greatly simplified and attack surfaces reduced. In this paper we present Mahiru, a design for a data exchange and processing system in which owners of data and software fully control their assets, users may submit a wide variety of processing requests including most of the above applications, and all parties collaborate to execute those requests in a distributed fashion, while ensuring that the policies are adhered to at all times. This is achieved through a federated, mostly decentralised architecture and a powerful policy mechanism designed to be easy to understand and simple to implement. We have created a proof-of-concept implementation of the system which is openly available and in continuous development, and which we aim to continue to extend with new functionality.
