  • FedEx CEO on Physical AI, the Big Bet on Data, and the Two Trillion-Dollar Supply Chain Problem
    3 Nov 2026
    Before 2020, few people thought about supply chains. The pandemic put them on every boardroom agenda, and trade and geopolitics now make them critical issues for every global company. Few businesses have a better view into what changed than FedEx.In this episode of TechSurge, host Michael Marks speaks with Raj Subramaniam, who has run FedEx since 2022 as only the second CEO in the company’s history after founder Fred Smith. The company moves close to 18 million packages a day across more than 220 countries and territories, roughly $2 trillion of goods a year.Subramaniam shares his perspective on “re-globalization”, describing a fundamental shift in trade patterns that began in 2025. He walks through the operational shock of the US ending de minimis treatment for low-value imports, which forced FedEx to formally clear six times as many packages and hire more than 2,000 people in a matter of weeks, and explains why the company has quietly opened new hubs and routes across Asia, the Middle East, and Latin America to stay ahead of shifting trade flows.The conversation turns to data and AI: FedEx scans 18 million packages roughly 20 times a day, generating two petabytes of data daily, which the company uses for everything from predictive logistics for hospital deliveries to an AI tool that picks the correct customs classification code for international shipments. Subramaniam also discusses FedEx’s expanding use of physical AI, including robotic trailer-loading partnerships with Dexterity and Berkshire Grey and nearly a million miles of autonomous trucking with Aurora in Texas, and makes the case that AI is adding jobs at FedEx rather than eliminating them.Marks and Subramaniam also discuss why Amazon is a FedEx customer rather than a competitor, the company’s recent spinoff of FedEx Freight, its new supply chain orchestration partnership with the US Army, and Subramaniam’s own 35-year career at FedEx, including his path as an immigrant who rose to lead the company.Sign up for our newsletter at techsurgepodcast.com for updates on upcoming TechSurge Live Summits and future episodes.Speaker Profiles and LinksMichael Marks: Founding Managing Partner, Celesta CapitalRaj Subramaniam: President and CEO, FedEx Wikipedia: https://en.wikipedia.org/wiki/Raj_SubramaniamLinkedInhttps://www.linkedin.com/in/rajeshsubramaniam1/ Further Reading and ResourcesWhite House – Executive Order 14324, ending de minimis duty-free treatment: https://www.whitehouse.gov/presidential-actions/2025/07/suspending-duty-free-de-minimis-treatment-for-all-countries/Supply Chain Dive – FedEx’s 2025 shipping agreement with Amazon: https://www.supplychaindive.com/news/fedex-amazon-new-shipping-contract-2025/747942/FedEx Newsroom – FedEx and Dexterity’s physical AI trailer-loading deployment: https://newsroom.fedex.com/newsroom/global-english/fedex-and-dexterity-expand-physical-ai-deployment-for-autonomous-trailer-loading-at-hagerstown-hubFedEx Newsroom – FedEx and Aurora autonomous trucking partnership: https://newsroom.fedex.com/newsroom/fedex-teams-up-with-aurora-and-paccar-to-test-autonomous-linehaul-technology/U.S. Army – Strategic Capital Initiative with FedEx Dataworks: https://www.army.mil/article/294805/army_launches_flagship_strategic_capital_initiative_with_fedex_dataworks_to_modernize_logistics_infrastructureFortune – Profile of Raj Subramaniam: https://fortune.com/2026/07/15/fedex-ceo-raj-subramaniam-tariffs-supply-chain-shipping-fortune-500-titans-and-disruptors-of-industry/Timestamps [00:00] Why Supply Chains Became a Boardroom Issue [00:38] Introducing Raj Subramaniam and FedEx [02:27] Is Today’s Trade Environment “Business as Usual”?

  • Patrick Pilarski: Alberta Plan Co-Author On Reinforcement Learning & AI-Powered Prosthetics
    21 Oct 2026
    In this episode, Dr. Patrick Pilarski, co-author of the Alberta Plan alongside Richard Sutton and Michael Bowling, makes the case for a radically different kind of AI: one that never stops learning, builds its own understanding from raw experience, and gets more out of limited compute rather than more data centers. A Canada CIFAR AI Chair (Amii) and professor at the University of Alberta, Pilarski also leads a lab that builds robotic prosthetic limbs that learn to anticipate what their users intend to do before they do it.In this conversation, Pilarski joins TechSurge to unpack why his co-author Rich Sutton has publicly called LLMs a dead end, how the Alberta Plan’s “temporal uniformity” differs from how today’s AI labs bolt reinforcement learning onto pre-trained models, and why he believes AI safety problems in today’s LLM agents are really reinforcement learning problems the field has studied for decades.The conversation covers:✅ Why Richard Sutton argues large language models are a dead end✅ The four core commitments of the Alberta Plan for AI research✅ Why “temporal uniformity” rejects the idea of separate training and deployment phases✅ Patrick’s upcoming move to ExperienceFlow.AI as Head of Edge Superintelligence✅ Why he doesn’t believe the AI data center build-out locks the industry into one path✅ How reinforcement learning’s lessons on exploration and reward specification apply to AI agent safety✅ Inside his lab’s work on AI-powered prosthetic limbs that predict user intent✅ Supernumerary limbs and the future of human augmentationGuest Links:Patrick Pilarski: Canada CIFAR AI Chair and Fellow at Amii, Professor in the Department of Medicine at the University of Alberta, co-author of the Alberta Plan, and co-lead of the BLINC Lab.

  • Gaming Chip Pioneer Raja Koduri on China's AI Cost Advantage and Moving Beyond the GPU
    29 Sep 2026

    In this episode, host David Goldman speaks with legendary graphics chip architect Raja Koduri, who explains why every gigawatt of AI infrastructure now costs $50 to $60 billion, and why China's goal of doing it for under $10 billion is the real threat to Western AI. Raja twice led graphics at AMD, directed Apple's graphics architecture and was chief architect at Intel. He argues that the real AI race isn't Nvidia vs. Google vs. Broadcom but China vs. the rest of the world, and that the new bottleneck isn't compute. It's memory.


    In this conversation, Raja joins TechSurge to talk about his new startup Oxmiq, which aims to turn "electrons to tokens super efficiently." He covers how 3D-stacked, hybrid-bonded memory could deliver 10x the bandwidth of today's HBM, why AI agents are changing how chips get designed, and why he thinks the next disruption to AI data centers "comes from the bottom."

    The conversation covers:

    ✅ Why every gigawatt of AI infrastructure costs $50 to $60 billion, and where the $45 billion in hardware spend goes

    ✅ The $24 trillion capital question: 400+ gigawatts of new compute needed by 2030

    ✅ How China's under-$10 billion per gigawatt target creates a 5 to 6x cost gap

    ✅ Why memory hierarchy, not raw compute, is now the real bottleneck in AI

    ✅ How advanced packaging can unlock 10x bandwidth and 10x token generation, even on older 7nm nodes

    ✅ Why OpenAI's Jalapeño chip shows that AI can speed up silicon design

    ✅ Why the value of experienced engineers has gone up 100x in the age of AI coding agents

    ✅ Leadership lessons from Steve Jobs at Apple and Lisa Su at AMD

    ✅ Why Intel's decision to kill 3D XPoint memory came at "the wrong time"

    ✅ Boom or bust: the financial engineering risk behind the AI infrastructure buildout

    ✅ Token factories vs. token banks: why "the more boring you make it, the more it becomes fabulous"
