7.- Kaelbling's work at SRI, including her involvement with robots like Shakey, contributed to her interest in foundational robotics research, underscoring the significance of early AI projects in her career.

8.- The concept of "situated automata" influenced her approach to robotics, focusing on the practical implementation of logical reasoning tools rather than their manipulation within a robot's "mind."

9.- Reinventing wheels in robotics was seen as beneficial by Kaelbling, as it allowed for a deeper understanding of good solutions after exploring less effective ones firsthand.

10.- The historical oscillation of AI research themes, from cybernetics to expert systems, illustrates the field's evolution and Kaelbling's perspective on the shifting focus of AI research over decades.

11.- Kaelbling emphasizes the importance of abstractions and decompositions in AI, highlighting how these concepts are critical for simplifying and managing the complexity of the world, allowing for more effective problem-solving and planning.

12.- The conversation delves into Partially Observable Markov Decision Processes (POMDPs), exploring how they model the uncertainty inherent in real-world scenarios, demonstrating Kaelbling's expertise in dealing with uncertainty in AI systems.

13.- Kaelbling discusses the challenges of planning under uncertainty, pointing out that while optimal solutions for POMDPs might be intractable, the real skill in AI lies in making practical approximations to tackle these complexities.

14.- The discussion shifts to the philosophical aspects of AI, exploring topics like the relevance of philosophical concepts such as belief and knowledge in AI research, highlighting the depth of Kaelbling's interdisciplinary approach.

15.- Kaelbling shares insights on the evolution of AI research, reflecting on the oscillations between different paradigms and methodologies, showing her comprehensive understanding of the field's history and its impact on current research directions.

16.- The role of perception in AI is discussed, with Kaelbling arguing that the representational challenges of perception are significant barriers to progress, illustrating her nuanced understanding of the limitations and potential of current AI technologies.

17.- The interview touches on the importance of aligning AI systems' objectives with human values, showcasing Kaelbling's awareness of the ethical implications of AI research and the need for careful consideration of AI systems' goals.

18.- Kaelbling explores the idea of belief space versus state space, illustrating her innovative approach to AI problem-solving by emphasizing the significance of managing uncertainty and information gathering in AI systems.
