From the early large language models (LLMs) to more sophisticated architectures like Agentic RAG and Physical AI systems, this chapter examines the revolutionary path of generative AI (Gen AI). To achieve artificial general intelligence (AGI), it highlights the necessity of quantum leaps in five areas: data, computing power, biological and bionic computing, physical capabilities, and energy infrastructure. This chapter raises serious ethical and privacy concerns by cautioning that current AI models will experience diminishing returns without exponentially larger and more varied data sources, such as behavioral and neural data. The “DeepSeek moment,” which represents the global democratization of AI, is an example of how technological moats are eroding. By imitating natural systems, advances in neuromorphic, biological, and quantum computing hold the potential to rethink machine intelligence completely. In the meantime, humanoid robotics and physical AI.
