Hello, everyone! Today, we’re diving into a topic that’s both fascinating and critical for the future of humanity—the intersection of artificial intelligence and warfare. We’re talking about machines making decisions on the battlefield, the risks involved, and the moral questions we face as AI becomes more powerful. This is based on the eye-opening work of Paul Scharre’s book, Army of None.
Paul takes us deep into the world of autonomous weapons and asks the tough questions: How do we keep humans in control? What happens when AI can make life-or-death decisions faster than any human ever could? And most importantly, what’s our responsibility as we embrace these technologies?
Today, we have an incredible group of voices joining us to break down these complex issues—Paul himself, along with leading experts from the fields of AI ethics, cybersecurity, and military strategy. So sit tight, because this is going to be a powerful conversation that you won’t want to miss!
Human Control in Autonomous Warfare: Lessons from Army of None
Nick Sasaki (Moderator):
"Welcome, everyone. Today, we’ll be discussing the importance of maintaining human control in autonomous warfare. Paul, your book Army of None stresses why humans need to remain ‘in the loop’ when it comes to lethal decisions. Could you start by explaining the essence of this argument?"
Paul Scharre:
"Thanks, Nick. The core of my argument is that while autonomous systems can be highly effective in increasing speed and precision, humans must remain in control of decisions regarding the use of lethal force. Machines lack moral judgment. They process data and act based on algorithms, but they can’t understand the human cost of war. Without human oversight, we risk creating systems that can make tragic, irreversible mistakes, such as targeting civilians or escalating conflicts based on misinterpreted data. Accountability is also a major issue—who’s responsible when a machine makes a fatal error?"
Nick Sasaki:
"That’s a critical point, Paul. Stuart, you’ve been an advocate for ethical AI development. How do you see this balancing act between leveraging AI in warfare and ensuring human control?"
Stuart Russell:
"Paul is absolutely right. The danger isn’t just the removal of human judgment but also the unpredictability of real-world situations that machines can’t fully understand. AI might misinterpret a scenario or respond inappropriately, leading to unintended harm. The ethical framework behind warfare relies on human accountability, and when we replace humans with machines in these decisions, we lose that foundation. There’s also the risk of escalation—autonomous systems could react faster than humans can intervene, potentially turning a small conflict into something much worse."
Nick Sasaki:
"Mary, you’ve been working with the Campaign to Stop Killer Robots, advocating for regulation. How does this conversation around human control align with the goals of your campaign?"
Mary Wareham:
"It aligns perfectly, Nick. Our campaign is focused on ensuring that no weapon system, especially those with lethal force, operates without meaningful human control. Autonomous systems should never be allowed to make decisions about life and death. We’re pushing for international regulations to mandate human oversight. The technology is advancing quickly, and unless we establish clear rules now, we may end up with systems that operate without accountability and transparency. It’s a dangerous road to go down."
Nick Sasaki:
"Paul, do you think there’s a path forward where we can innovate with AI while still keeping human control intact?"
Paul Scharre:
"I do, but it requires discipline and foresight. We need to ensure that autonomous systems are designed to assist, not replace, human decision-making. This means keeping humans at the center of critical decisions, especially when it comes to lethal force. Additionally, we need strong regulatory frameworks at both national and international levels to ensure that the temptation to remove human oversight in the name of efficiency doesn’t take hold. Ultimately, it’s about using technology responsibly and remembering that machines should serve humanity, not make the most crucial decisions for us."
Speed vs. Control: Managing Autonomous Systems in Hypersonic Warfare
Nick Sasaki:
"Our next topic dives into the challenge of balancing speed and control in hypersonic warfare. As autonomous systems become faster, humans are being pushed out of the decision-making loop because they can’t keep up with the pace. Paul, can you explain how speed impacts the risk of losing human control in modern warfare?"
Paul Scharre:
"Absolutely, Nick. The faster autonomous systems operate, the more difficult it becomes for humans to stay involved in critical decisions. Hypersonic missiles, for example, travel at such extreme speeds that humans often have mere seconds to decide how to respond. The risk is that militaries will be tempted to let these systems act on their own, without human intervention, to maximize speed and reaction times. But this comes with significant risks. Machines are fast, but they’re also prone to errors, and without human oversight, the consequences could be disastrous. A system might misinterpret data or mistakenly engage in combat, leading to unintended escalations or civilian casualties."
Nick Sasaki:
"That’s a real dilemma. Elon, you’ve raised concerns in the past about AI’s role in warfare. How do you think this increasing speed impacts the potential dangers of autonomous systems?"
Elon Musk:
"Thanks, Nick. The problem with speed is that it pushes humans out of the loop. The faster systems operate, the less time humans have to intervene when things go wrong. And when we hand over control to machines, especially in warfare, we’re taking a massive risk. Autonomous systems can make split-second decisions based on data, but they lack context and understanding. In high-speed situations, if an AI system makes a mistake—like targeting the wrong object—there’s no time for humans to step in and correct it. That’s where the real danger lies. Once these systems are deployed at full speed, we’re relying on them to always be correct, and that’s just not a safe assumption."
Nick Sasaki:
"Missy, as someone who’s worked with these systems, what’s your perspective on balancing the need for speed with the requirement for human oversight?"
Missy Cummings:
"Speed definitely complicates things, Nick, but it doesn’t mean we have to give up control entirely. One solution is to use AI to assist human decision-making, rather than fully replace it. For example, AI systems can process massive amounts of data and provide rapid recommendations, but humans should still make the final call. We can also design fail-safes into these systems, where they pause or ask for human input if they encounter uncertainty. The challenge is maintaining human control without sacrificing too much speed, and that requires smarter designs that balance both."
Nick Sasaki:
"Paul, given the risks we’ve discussed, do you think it’s possible to develop autonomous systems that operate at these high speeds while still keeping humans meaningfully involved?"
Paul Scharre:
"It’s possible, but difficult. As Missy mentioned, we need to develop systems that complement human decision-making rather than replace it. That could mean designing AI that gives humans more context or extra time to make decisions in high-speed scenarios. But what we cannot do is allow speed to become the driving factor in warfare at the expense of human oversight. It’s a tricky balance, but it’s essential for ensuring that autonomous systems act responsibly and ethically."
The Autonomous Arms Race: Did Scharre’s Predictions Come True?
Nick Sasaki:
"Let’s move on to our next topic: the autonomous arms race. In Army of None, Paul warned about the risks of an AI-driven arms race in warfare. With autonomous weapons now being developed by multiple nations, we need to ask: Have these predictions come true? Paul, could you start by explaining your thoughts on how this arms race is playing out in 2024?"
Paul Scharre:
"Thanks, Nick. Unfortunately, the predictions I made about an autonomous arms race are already starting to materialize. Countries like the U.S., Russia, and China are developing increasingly sophisticated AI weapons systems. The challenge is that once one nation develops these systems, others feel they need to keep pace to avoid being left behind. This creates a race where the focus is more on who can develop the most advanced system rather than ensuring those systems are safe, ethical, and accountable. The lack of international regulation is making this worse, as countries are hesitant to cooperate on restrictions that might put them at a strategic disadvantage."
Nick Sasaki:
"That sounds like a dangerous path. Vladimir, Russia has been a key player in developing these systems. How do you see this arms race playing out, and is there a way to prevent it from escalating further?"
Vladimir Putin:
"Russia views AI and autonomous weapons as critical to maintaining global security. We must ensure we are not left behind in this technological evolution. However, Paul is right—there is a risk in allowing this arms race to spiral out of control. What we need is an international framework that balances security with restraint. Autonomous weapons offer strategic advantages, but if we let them proliferate without oversight, it could destabilize the global order. We must work together to ensure these systems are used responsibly."
Nick Sasaki:
"Mary, from your perspective advocating for regulation, how does this autonomous arms race impact efforts to establish international controls? Is there any progress being made?"
Mary Wareham:
"The autonomous arms race makes regulation even more critical but also more difficult. Nations are reluctant to agree to restrictions when they feel like their competitors are racing ahead. While we’ve made some progress in bringing attention to the issue, especially through forums like the U.N., the reality is that most major military powers are not ready to commit to binding agreements. The lack of trust between nations is a big obstacle. That said, smaller nations and civil society groups are pushing for stronger regulations, which is a positive step, but we need the major players on board."
Nick Sasaki:
"Paul, what do you think is the next step to prevent this arms race from getting out of control? Can international regulation catch up, or are we already too far down this path?"
Paul Scharre:
"It’s not too late, but we need to act quickly. The first step is building trust between nations through transparency. Countries need to openly share what they’re developing and how they plan to use these systems. This can help prevent misunderstandings and reduce the likelihood of conflicts escalating. The second step is establishing clear international norms or treaties that limit the development of fully autonomous weapons systems. We’ve done this with other dangerous technologies, like nuclear and chemical weapons, and we can do it here too. The key is making sure we don’t wait until it’s too late."
AI Vulnerabilities in Combat: Learning from Army of None
Nick Sasaki:
"Next, we’ll discuss the vulnerabilities of AI in combat, a topic Paul explores in Army of None. As autonomous systems become more prevalent, they also become more susceptible to hacking, manipulation, and failure. Paul, can you explain the key risks that AI systems face in a combat environment?"
Paul Scharre:
"Thanks, Nick. One of the biggest risks with autonomous systems is their susceptibility to adversarial attacks. These systems rely on vast amounts of data and algorithms to make decisions, but if that data is manipulated or compromised, the AI can make catastrophic mistakes. For example, adversaries could spoof or jam signals, tricking an AI system into identifying a false target. This could lead to unintended engagements or civilian casualties. Additionally, autonomous systems are vulnerable to cyberattacks. A hacker could take control of a drone or other autonomous weapon, using it against its own operators. The more we rely on AI in combat, the greater these vulnerabilities become."
Nick Sasaki:
"That’s a scary scenario. Bruce, as a cybersecurity expert, what are the most pressing vulnerabilities in AI systems that militaries should be concerned about?"
Bruce Schneier:
"Paul’s absolutely right. AI systems in warfare are particularly vulnerable because they’re often built to make decisions autonomously, without a lot of human oversight in real time. That means once they’re in operation, they can be difficult to monitor or correct. One of the biggest issues is adversarial machine learning, where an attacker subtly changes the input data to fool the AI into making the wrong decision. For example, in a battlefield scenario, an attacker might feed the system manipulated data, making it think friendly forces are enemies or vice versa. Cybersecurity in AI is still playing catch-up, and the military needs to be aware of how these systems can be exploited."
Nick Sasaki:
"Dmitri, given your experience in tracking cyber threats, how do you see AI vulnerabilities affecting military strategies in the future?"
Dmitri Alperovitch:
"Nick, the issue isn’t just with direct attacks on AI systems, but also with the reliability of these systems in unpredictable environments. AI is great at analyzing patterns, but it struggles when it encounters situations it hasn’t been trained for. This creates opportunities for adversaries to exploit those gaps. Hackers could potentially introduce unexpected variables into the system that confuse it or cause it to behave erratically. The bigger challenge for militaries will be finding ways to secure their autonomous systems against these types of cyberattacks and building resilience into the AI so it can still function even when under attack."
Nick Sasaki:
"Paul, you’ve talked a lot about the need for resilience and security in AI systems. What steps do you think the military should take to protect these systems from being exploited in combat?"
Paul Scharre:
"Great question, Nick. The first step is redundancy. We need to design systems that don’t rely on a single point of failure. If one system is compromised, there should be backup systems or human operators who can step in and take over. Second, we need to build AI that is more transparent, so operators can understand why a system is making a particular decision. That way, if something seems off, humans can step in before things go wrong. Finally, there’s a need for rigorous cybersecurity protocols that account for the unique vulnerabilities of AI systems. It’s not enough to secure these systems from traditional cyber threats; we also need to guard against the specific risks that come from using machine learning in unpredictable combat environments."
Human-Machine Teaming: Scharre’s Vision in Practice
Nick Sasaki:
"For our final topic, we’ll discuss the future of human-machine teaming in warfare, an idea Paul presents in Army of None. Rather than seeing AI as a replacement for humans, Paul advocates for systems that work alongside human operators. Paul, could you start by explaining your vision for human-machine collaboration in combat?"
Paul Scharre:
"Thanks, Nick. The idea behind human-machine teaming is to combine the strengths of both humans and AI, rather than having AI fully replace human decision-makers. Humans bring creativity, moral judgment, and adaptability, while machines offer speed, data processing, and the ability to operate in environments that are too dangerous for humans. By working together, human operators can leverage the strengths of AI to make better decisions while ensuring that moral and strategic oversight remains intact. For instance, AI can process vast amounts of battlefield data in real time and present options to human commanders, who can then use their judgment to make the final call. This ensures that humans remain central in critical decision-making."
Nick Sasaki:
"That’s a nuanced approach. Eric, given your work with the U.S. National Security Commission on AI, how do you see this vision of human-machine teaming evolving in real-world military operations?"
Eric Schmidt:
"Paul’s vision is exactly where we need to be headed. The future of warfare will increasingly depend on how well humans and machines can work together. AI can handle tasks that require speed and precision, like data analysis or targeting, while humans provide the ethical and strategic oversight that machines lack. The real challenge is making sure the human-machine interface is seamless. That means designing systems that are intuitive and provide human operators with the information they need in a clear, actionable way. We don’t want to overwhelm humans with too much data; we want to empower them to make faster, better-informed decisions."
Nick Sasaki:
"Fei-Fei, as someone who has worked extensively on AI development, how do you see human-machine teaming being implemented effectively, especially in high-pressure situations like combat?"
Fei-Fei Li:
"Nick, human-machine teaming requires a fundamental shift in how we think about AI. Instead of viewing AI as a tool that replaces human tasks, we need to design it to complement human abilities. In high-pressure environments, AI should act as a co-pilot that assists but never takes over completely. This requires building AI systems that can interpret complex, uncertain environments and then communicate their findings to humans in a way that’s easy to understand. The ultimate goal is to create trust between the human and the machine. Humans need to feel confident that the AI is providing them with reliable, useful information, and AI needs to be able to adjust its behavior based on human input."
Nick Sasaki:
"Paul, given the challenges and opportunities that Eric and Fei-Fei mentioned, what do you think is the most important aspect of developing successful human-machine teams in warfare?"
Paul Scharre:
"The most important aspect is trust. For human-machine teaming to work, human operators need to trust the AI, and that trust is built through transparency, reliability, and training. Operators need to understand how the AI works and why it’s making certain recommendations. That’s why designing transparent AI systems is critical. We can’t treat AI as a black box; operators need insight into the AI’s decision-making process. At the same time, rigorous training is needed to ensure that humans know how to work effectively with these systems. This isn’t just about training on the technology, but also on how to make decisions in tandem with AI. The goal is to create teams where AI enhances human abilities, rather than replacing them."
