Original Air Date: November 14, 2025

Brief Overview

This episode explores the intersection of modern warfare, artificial intelligence (AI), and entrepreneurship. Rob Young sits down with Will Blythe, former British Army officer and now CEO of Arundight, a UK-based AI defense technology company. Together, they delve into Blythe's military background, the rapid evolution of battlefield technology—particularly in light of recent conflicts like Ukraine—and the profound ethical and practical challenges involved in arming democracies with the latest tech while keeping humans in the loop.

Key Discussion Points & Insights

1. From Soldier to Defense Entrepreneur

• Military Origins:
  • Blythe describes his middle-class upbringing and early attraction to public service, initially through the army or possibly medicine.
  • He joined the British Army at a time when peacekeeping shifted to prolonged combat following 9/11.
  • Quote:
    • “Somehow these had some equivalence of linked to public Service and a desire to try to. To do something, to give back to society early on.” — Will Blythe [02:20]
• Combat and Learning Process:
  • His first Afghanistan tour (2009) was “quite an intense combat tour … one of the most intense … in the whole campaign.”
  • Gained firsthand experience about modern warfare and caring for those under his command.
  • Career evolved into various roles, culminating at the Ministry of Defence in urgent procurement.
  • Quote:
    • “People don't understand about the military necessarily, who haven't been in the army, it's not really one job. You're moving through different jobs all the time.” — Will Blythe [03:38]

2. Transition to Technology & Founding Arundight

• Leaving the Military:

  • After 12 years, Blythe saw advancing technology as a new frontier for serving society.
  • He believed he could do just as much from the outside:
    • “It was clear to me that an important way to continue to serve was in making sure that many of these technologies could get into people's hands more quickly.” — Will Blythe [04:45]

• The Impact of Ukraine:

  • Russia’s 2022 invasion of Ukraine underscored the need for rapid advancement in defense technology.

• Naming the Company:

  • “It’s really hard to name a company… Arondite is the sword used by Sir Lancelot in the Arthurian legend. We thought that was as good a name as any, plus it was free and available.” — Will Blythe [05:55]
  • The name symbolizes purpose and higher mission.

3. The Changing Face of Warfare

• From “Big Kit” to Networked Systems:

  • Shift from small numbers of crewed, expensive systems to complex networks of affordable drones, robots, and sensors.
  • “There’s been a move towards increasing numbers of disparate robotic systems, drones, sensors... an enormous growth and added complexity from all these new pieces of equipment.” — Will Blythe [07:42]

• Key Challenges Identified:

  • Integration: Connecting new, “off-the-shelf” devices quickly on the battlefield.
  • Data Overload: Interpreting numerous, real-time streams from diverse devices.
  • Human-Machine Teaming: Scaling meaningful human control and judgment even as machine autonomy rises.
  • Quote:
    • “How do you make sure that these blended teams of humans and robots can work together … in a way that scales up a human’s ability to have meaningful control?” — Will Blythe [09:02]

4. Arundight’s Role & Technology in Practice

• Product in Use:
  • Blythe describes the firm’s AI software being operational with the UK military in Latvia.
  • Focus is on connecting sensors, robotics, and traditional systems for faster, more effective battlefield reactions.
    • “Something as simple as [automated drone deployment] … at the speed that we can make it happen, can make the difference between losing a battle and winning a battle.” — Will Blythe [12:38]

5. Ethics, Human Control, and AI Risks

• Keeping Humans “In the Loop”:

  • Blythe is emphatic about centrality of human judgment in potential lethal decisions.
  • AI assists with identifying and interpreting, but humans must approve any use of force.
    • “Making sure that the human users remain central to the way that robotic systems are being used by Defence… you have to make sure … that they can take a decision related to any, any targeting on the battlefield.” — Will Blythe [14:20]

• Values and Legal Norms:

  • Stresses obligation to pursue speed and operational effectiveness without sacrificing ethics.
  • “Democratic countries … have expected their armed forces to abide by codes of conduct and by a whole range of legal norms... we have to overcome [the idea of] zero sum trade offs … between speed and ethics.” — Will Blythe [14:56]

6. Who Gets the Technology?

• Sales Restrictions:
  • Arundight will not sell to China, Russia, or non-democratic countries.
  • “It is such a hard no. I just want to make it overwhelmingly clear that is absolutely not the point of the company. … We know which side we’re on for sure.” — Will Blythe [17:18]

7. Leadership, Company Culture, and the Future

• Military vs. Tech Startup Life:

  • Blythe dismisses stereotypes of military regimentation—believes modern command is about enabling smart people, not commanding them.
    • “I don’t think I’m in charge of our software engineers. I think we bring on incredibly smart people … and we create the conditions for them to innovate and invent.” — Will Blythe [18:04]

• Company Growth and Mission:

  • Having raised over $12 million, their urgent objective is to “expand the company as quickly as possible” to have defensive impact for democracies.
  • “We feel that we’re against the clock every single day to grow the company as fast as possible.” — Will Blythe [19:05]

Notable Quotes & Memorable Moments

• “We exist as a company to make sure that the democratic countries who share our values have the tools they need to keep our societies safe.” — Will Blythe [01:46]
• “When they’re face down in the mud and you’ve got a rifle in one hand and a radio in the other ... you’re not giving them some kind of extra tech that’s just totally unreasonable ... in that situation.” — Will Blythe [06:20]
• On ethics in warfare tech:
  • “You have to make sure that the way you’re solving this is worthy of the values that you’re seeking to defend.” — Will Blythe [14:32]
• On AI in warfare:
  • “Everything about the use of artificial intelligence on the battlefield needs to be approached with, with a sober, careful and responsible mindset ... I don’t see anyone in the defence industry who’s in some way flippant about this stuff or taking an irresponsible approach.” — Will Blythe [15:57]
