David Patterson: Computer Architecture and Data Storage | Lex Fridman Podcast #104 | Lex Fridman

Lex Fridman interviews David Patterson, a Turing Award winner and computer science professor, about the evolution of computers over the past 50 years, focusing on microprocessor architecture, RISC vs CISC, and the impact of Moore's Law. Patterson explains the layers of abstraction in computers, the design of instruction sets, and the rise of open-source hardware like RISC-V. The conversation covers the shift towards domain-specific architectures, the role of machine learning, and the importance of metrics like MLPerf. Patterson also shares insights on RAID storage, the balance between teaching and research, and life lessons learned from wrestling, ending with a reflection on the importance of relationships and personal values.
