FAA Ground Stop Revives Gary Marcus's AI Warnings
Start here
Gary Marcus, a longtime critic of generative AI in critical systems, linked the nationwide FAA ground stop and a major Microsoft outage this week to warnings he says he has issued since 2022. In his account, it is still unclear whether the FAA incident was the malicious cyberattack he warned about in a January 2025 Politico piece or the kind of large language model failure he flagged in May 2022. Marcus frames both incidents as evidence for his argument that generative AI should not be placed in charge of critical infrastructure, and he attributes the risk to what he calls Silicon Valley arrogance. His post does not establish the cause of either outage; it presents the two possibilities as open questions.
