Richard Grisenthwaite, Executive Vice President and Chief Architect at Arm Holdings, has recently emphasized the importance of trust and security in the development of AI systems. In a November 2025 keynote at the IoT Security Foundation conference, he argued that a large portion of cybersecurity challenges in AI are not unique to the technology, and that existing security measures, such as memory safety and protection against code reuse attacks, remain relevant. He also noted that the current AI industry is in an investment phase, with monetization still to come, and predicted that efficiency concerns will drive more AI processing to the edge. Grisenthwaite has also been involved in promoting hardware security innovations, particularly the CHERI architecture and the Morello prototype, which aim to mitigate software vulnerabilities through processor design. In earlier remarks, he described these as collaborative efforts with academia and government, emphasizing that they are experimental platforms rather than commercial products, and expressed hope that such technologies could eventually become mainstream in processor architectures across the industry. He has also highlighted security as a critical challenge for computing, citing projected cybercrime losses and the need for trustworthy infrastructure in an increasingly connected world.
