Joscha Bach (born 1973) is a German cognitive scientist, AI researcher, and philosopher known for his work on cognitive architectures, artificial intelligence, mental representation, emotion, social modeling, multi-agent systems, and the philosophy of mind. He is a prolific thinker whose research aims to bridge cognitive science and AI by studying how human intelligence and consciousness can be modeled computationally.

Contents

Early life and education

Bach was born in Weimar, East Germany, and displayed an early interest in philosophy, artificial intelligence, and cognitive science. He received an MA (computer science) from Humboldt University of Berlin in 2000 and a PhD (cognitive science) from Osnabrück University in 2006, [1] [2] [3] where he conducted research on emotion modeling and artificial minds. His doctoral work focused on developing micropsi, a cognitive architecture designed to simulate human-like reasoning and decision-making processes.

Career

After completing his Ph.D., Bach became a key figure in AI research, especially in cognitive architectures and the computational theory of mind. [4] He has held a variety of positions in both academic and industrial research, contributing to AI development from both theoretical and applied perspectives. [5] His work frequently explores the boundaries of AI systems, questioning the limits of current machine learning technologies and addressing how future systems might achieve human-like general intelligence. [6]

Bach has worked in several prestigious institutions, including the Harvard Program for Evolutionary Dynamics, where he collaborated with other thought leaders in AI and cognitive science. [7] He has also held research positions at the MIT Media Lab [8] and has served as a vice president of research at AI Foundation, where he has focused on developing AI systems capable of more sophisticated, human-like interactions. [9]

Research and Contributions

Joscha Bach's research is largely centered on cognitive architectures—computational models that attempt to replicate aspects of human cognition. [10] His work includes:

MicroPsi

A cognitive architecture that models how agents think and act based on perception, emotion, and goal-driven behavior. [11] Bach designed MicroPsi to simulate human-like reasoning and decision-making, contributing to AI systems that can navigate complex, real-world environments. [12]

Theories of Consciousness

Bach is well known for his discussions on the nature of consciousness and the computational modeling of subjective experience. [13] He argues that consciousness emerges from an information-processing system capable of creating internal models of itself and the world. He emphasizes the importance of mental models, emotional frameworks, and meta-cognition in the construction of conscious AI. [14]

Cognitive Limitations of AI

Bach has been a vocal critic of the current trends in machine learning, particularly the limitations of deep learning in creating truly intelligent systems. He contends that AI systems today lack understanding and operate more like "super-powered pattern recognition machines" than true cognitive agents. [15] He advocates for a move beyond current AI paradigms to develop machines capable of abstract reasoning, complex decision-making, and internal self-reflection. [16]

Consciousness and Free Will

In addition to his technical research, Bach is deeply engaged with philosophical questions surrounding consciousness and free will. He suggests that consciousness is an emergent property of highly complex information-processing systems that develop internal models of themselves and the world around them. [17] He often debates whether free will truly exists or is merely a byproduct of predictive models constructed by our brains—a question with implications for future AI systems.

Philosophical Views

Bach's intellectual curiosity extends beyond AI and cognitive science to touch on deeper questions about consciousness, free will, the nature of reality, and the future of humanity in an age of intelligent machines. [18] His work is heavily influenced by philosophical discussions about phenomenology and epistemology. [19] He frequently engages in debates on the nature of the self, arguing that what we consider "self" is an illusion—a mental model constructed by the brain for practical purposes. [20]

Bach also envisions a future where AI might possess meta-cognition—the ability to be aware of its own thought processes and to reflect on them. [21] He suggests that while machines might achieve some level of subjective awareness, true consciousness in AI might only emerge when these systems can integrate their own experiences into a continuous narrative, much like humans do. [22]

He asserts that while today's AI systems are powerful, they are far from general intelligence. [23] He frequently discusses the limitations of AI, asserting that current AI lacks understanding or any true conception of the world around it. [24] He has been a prominent critic of overhyping deep learning models, advocating instead for more nuanced approaches that incorporate cognitive models, emotion modeling, and ethical considerations into AI research. [25]

Popularization and Public Speaking

In addition to his academic work, Bach is a prolific speaker and communicator who regularly shares his insights on cognitive science, AI, and philosophy. [26] He has given numerous talks at conferences, including TEDx, where he has covered topics such as the nature of intelligence, the future of AI, and the possibility of creating conscious machines. [27]

Bach is also an active participant in online discussions about AI and consciousness, appearing in podcasts, interviews, and public lectures. [28] He is known for his ability to explain complex ideas in accessible ways, making him a popular figure in the growing dialogue surrounding artificial general intelligence (AGI) and the future of human-machine interaction. [29]

Key Publications and Works

Principles of Synthetic Cognition

In this seminal work, Bach outlines the foundational principles of synthetic cognition, discussing how cognitive architectures could be designed to replicate human thought processes. [30]

Micropsi Cognitive Architecture

A detailed exposition of the Micropsi system, Bach's work in this area has been influential in shaping research in agent-based modeling and AI decision-making frameworks. [31] [32]

Cognitive science is the interdisciplinary, scientific study of the mind and its processes. It examines the nature, the tasks, and the functions of cognition. Mental faculties of concern to cognitive scientists include perception, memory, attention, reasoning, language, and emotion; to understand these faculties, cognitive scientists borrow from fields such as psychology, artificial intelligence, philosophy, neuroscience, linguistics and anthropology. The typical analysis of cognitive science spans many levels of organization, from learning and decision-making to logic and planning; from neural circuitry to modular brain organization. One of the fundamental concepts of cognitive science is that "thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structures."

Artificial consciousness, also known as machine consciousness, synthetic consciousness, or digital consciousness, is the consciousness hypothesized to be possible in artificial intelligence. It is also the corresponding field of study, which draws insights from philosophy of mind, philosophy of artificial intelligence, cognitive science and neuroscience.

Artificial general intelligence (AGI) is a type of artificial intelligence (AI) that matches or surpasses human cognitive capabilities across a wide range of cognitive tasks. This contrasts with narrow AI, which is limited to specific tasks. Artificial superintelligence (ASI), on the other hand, refers to AGI that greatly exceeds human cognitive capabilities. AGI is considered one of the definitions of strong AI.

A cognitive architecture refers to both a theory about the structure of the human mind and to a computational instantiation of such a theory used in the fields of artificial intelligence (AI) and computational cognitive science. These formalized models can be used to further refine comprehensive theories of cognition and serve as the frameworks for useful artificial intelligence programs. Successful cognitive architectures include ACT-R and SOAR. The research on cognitive architectures as software instantiation of cognitive theories was initiated by Allen Newell in 1990.

Unified Theories of Cognition is a 1990 book by Allen Newell. Newell argues for the need of a set of general assumptions for cognitive models that account for all of cognition: a unified theory of cognition, or cognitive architecture. The research started by Newell on unified theories of cognition represents a crucial element of divergence with respect to the vision of his long-term collaborator, and AI pioneer, Herbert Simon for what concerns the future of artificial intelligence research. Antonio Lieto recently drew attention to such a discrepancy, by pointing out that Herbert Simon decided to focus on the construction of single simulative programs that were considered a sufficient mean to enable the generalisation of “unifying” theories of cognition. Newell, on the other hand, didn’t consider the construction of single simulative microtheories a sufficient mean to enable the generalisation of “unifying” theories of cognition and, in fact, started the enterprise of studying and developing integrated and multi-tasking intelligence via cognitive architectures that would have led to the development of the Soar cognitive architecture.

An artificial brain is software and hardware with cognitive abilities similar to those of the animal or human brain.

Computational cognition is the study of the computational basis of learning and inference by mathematical modeling, computer simulation, and behavioral experiments. In psychology, it is an approach which develops computational models based on experimental results. It seeks to understand the basis behind the human method of processing of information. Early on computational cognitive scientists sought to bring back and create a scientific form of Brentano's psychology.

A wetware computer is an organic computer composed of organic material "wetware" such as "living" neurons. Wetware computers composed of neurons are different than conventional computers because they use biological materials, and offer the possibility of substantially more energy-efficient computing. While a wetware computer is still largely conceptual, there has been limited success with construction and prototyping, which has acted as a proof of the concept's realistic application to computing in the future. The most notable prototypes have stemmed from the research completed by biological engineer William Ditto during his time at the Georgia Institute of Technology. His work constructing a simple neurocomputer capable of basic addition from leech neurons in 1999 was a significant discovery for the concept. This research was a primary example driving interest in creating these artificially constructed, but still organic brains.

Psi-theory, developed by Dietrich Dörner at the University of Bamberg, is a systemic psychological theory covering human action regulation, intention selection and emotion. It models the human mind as an information processing agent, controlled by a set of basic physiological, social and cognitive drives. Perceptual and cognitive processing are directed and modulated by these drives, which allow the autonomous establishment and pursuit of goals in an open environment.

The LIDA cognitive architecture attempts to model a broad spectrum of cognition in biological systems, from low-level perception/action to high-level reasoning. Developed primarily by Stan Franklin and colleagues at the University of Memphis, the LIDA architecture is empirically grounded in cognitive science and cognitive neuroscience. It is an extension of IDA, which adds mechanisms for learning. In addition to providing hypotheses to guide further research, the architecture can support control structures for software agents and robots. Providing plausible explanations for many cognitive processes, the LIDA conceptual model is also intended as a tool with which to think about how minds work.

Cognitive computing refers to technology platforms that, broadly speaking, are based on the scientific disciplines of artificial intelligence and signal processing.
