Are you casually adopting AC adapters just because they are cheap? AC adapters carry inherent risks of electric shock and smoke or fire hazards, and incidents of fires due to design flaws from choosing low-cost products have occurred. When accidents involving electric shock or smoke and fire occur, not only do they lead to significant costs for post-incident handling and recall responses, but they also result in a decline in brand image, which can severely impact management. Therefore, it is essential to eliminate defect risks at the adoption stage. In this webinar, we aim to provide insights for evaluation during the adoption process by introducing case studies of market failure analysis of AC adapters that our company has experienced over the past several decades. We explain the content as simply and clearly as possible, so even those without prior knowledge of AC adapters are welcome to attend.

[Speaker] Shota Imai, President and CEO of GenesisAI, Inc. / Visiting Professor at the Graduate School of Advanced Science and Technology, Hokuriku University [Key Lecture Content] Generative AI is likely the greatest technological revolution in human history. As of 2025, generative AI possesses knowledge comparable to that of PhD holders and is capable of generating moving images that take physical laws into account. Furthermore, generative AI, which was previously focused on content generation, has evolved into AI agents capable of handling lengthy and complex tasks, enabling automation in research, software development, and scientific inquiry. While there are significant economic benefits from increased productivity, the concern of "losing jobs to AI" has become a realistic issue. This lecture will explain the outlook for the development of these AI technologies and their impact on society based on research conducted as of 2025. [Lecture Items] 1. Latest Research on Generative AI 2. Latest Research on AI Agents 3. Physical AI and World Models 4. Future Prospects for AI Development Based on Scaling Laws 5. AI for Scientific Research 6.
