Bruce Schneier
Security Technologist
The world’s best-known security technologist has spent years warning that corporate AI systems are “double agents” — spying on and manipulating users for their owners — and pressing governments to force trustworthiness on the industry.
In his words
We use all of these services as if they are our agents, working on our behalf. In fact, they are double agents, also secretly working for their corporate owners.
Corporations are not moral; they are precisely as immoral as the law and their reputations let them get away with.
Biography
Bruce Schneier (born 1963) is the security world’s public intellectual: author of the classic Applied Cryptography, designer of the Blowfish and Twofish ciphers, Harvard Kennedy School lecturer, and writer of the long-running Schneier on Security blog. The Economist once called him a “security guru,” and for three decades his specialty has been explaining how technical systems fail the people who trust them.
Double agents and category errors
His December 2023 essay “AI and Trust” frames his core charge: society will mistake AI chatbots for friends when they are corporate services, and the companies controlling them will exploit that confusion. His answer is regulatory — transparency laws, safety laws, and rules that force AI systems to actually work for their users. In parallel essays he warned that AI upgrades surveillance into something worse: automated mass spying that can summarize and interpret everyone’s conversations at once.
They won’t be our friends. At best, they’ll be useful services. More likely, they’ll spy on us and try to manipulate us.
Schneier is no doomer about the technology itself. His 2025 MIT Press book Rewiring Democracy (with Nathan E. Sanders) explores how AI could distribute rather than concentrate democratic power, and reviewers noted its guarded optimism about AI’s capabilities. His target is unaccountable corporate control, not the models — the same distinction drawn by critics like Meredith Whittaker. But the through-line of his public program is opposition: warning after warning that today’s AI, as built and deployed, cannot be trusted.
