FIREWALL with Bradley Tusk
Episode: Get Unstuck
Guest: Judah Taub (Managing Partner, Hetz Ventures; Author: "How to Move Up When the Only Way Is Down")
Date: May 7, 2026
Episode Overview
This episode features a conversation between host Bradley Tusk and Judah Taub, a prominent Israeli cybersecurity investor and recent author. The discussion explores the intersection of artificial intelligence (AI) and cybersecurity, the changing demands of tech infrastructure, and how concepts from AI and machine learning (like local maxima) can be applied to human decision-making, entrepreneurship, and broader societal challenges. The episode also touches on questions of resilience, collective versus individual good, and business agility—all in the context of rapid technological change.
Key Discussion Points & Insights
1. Judah Taub’s Background and Hetz Ventures’ Focus
[00:41-02:55]
- Judah describes his transition from UK-born Israeli military intelligence, hedge fund data head, to leading early-stage VC investments in Israel, focusing on AI, data, and cybersecurity infrastructure.
- Hetz Ventures specializes in investing in "infrastructure software," with an emphasis on AI and cybersecurity—areas where Israel has a historical advantage due to talent pools developed in the military.
Notable Quote:
"We call it infrastructure software... not at the application layer... [but] a layer below that that business owners are worried about optimizing... historically, and I think still very much today, Israel is good at." — Judah Taub (02:02)
2. The Convergence of AI and Cybersecurity
[02:56-05:46]
- AI and cybersecurity are merging—AI is both a new vector for attacks and for defense.
- Older cybersecurity solutions (think early antivirus) aren’t designed for the complexities of today’s AI-powered threats.
- The "attack surface" is expanding exponentially, calling for fundamentally different security solutions.
Notable Quote:
"Some of these AI companies are providing both cybersecurity attack verticals and defense verticals that the cyber companies themselves didn't imagine... we’re going to need to see very, very different types of solutions." — Judah Taub (03:11)
[04:27-05:46]
- Simply "pivoting" legacy products to claim they're AI-enhanced misses the point; real innovation requires a ground-up rethink.
3. Human Error vs. AI-Generated “Error” in Cybersecurity
[05:24-06:19]
- Previously, human error was the predominant cause of security breaches.
- As code generation shifts from human to AI (soon 90% AI-generated), risk moves from human blunders to systemic, AI-level risks.
Notable Quote:
"When 50, then 60, then 80, and soon 90% of the code is going to be written by AI, saying that all the mistakes are going to come from human error... it just doesn't make sense." — Bradley Tusk (05:38)
4. Future of Security Solutions: Endpoint Management & Agentic Systems
[06:59-10:25]
- A key security challenge: the shift from human users to AI agents (e.g., LLMs performing tasks autonomously) massively increases complexity in access management.
- The next wave of cybersecurity must manage orders of magnitude more agent interactions—not just humans—requiring radical rethinking of endpoint security.
Notable Quote:
"In an agentic world, you probably have more agents and... different order of magnitude of agents running within your system and you need to manage their accesses... the endpoint management system is going to be very different.” — Judah Taub (07:57)
- Companies like Google already layer multiple security systems and will need to hybridize during this transition.
5. Practical Security Advice for Businesses of All Sizes
[10:25-12:17]
- Businesses should choose security solutions based on their operational reality: Are they already deploying AI agents or not?
- Forward-thinking companies may adopt newer, agent-focused products sooner; laggards may benefit from waiting out a year as the space matures.
6. Applying AI/ML Concepts to Human Decisions: "Local Maximum" & Stuckness
[12:17-18:00]
- Judah introduces "local maximum": When optimizing (in business or life), it’s easy to climb a local peak, only to realize it isn’t the highest.
- To find better outcomes, sometimes you have to descend ("take losses") before reaching a superior summit ("global maximum").
Notable Quote:
"You get to the top... only to realize that there is a taller peak somewhere else. You are now stuck in a local maximum... any step you take... is going to necessarily have to be down." — Judah Taub (13:06)
- The sunk cost fallacy often traps people at "local maxima." True progress requires a willingness to sacrifice status or comfort for bigger opportunities.
7. Techniques from AI for Getting Unstuck: ABX (A/B/X) Testing
[18:23-20:37]
- Standard A/B testing iteratively optimizes but can trap people/algorithms on a single mountain.
- Inserting “X” (radically different options) can reveal new, higher peaks—innovation through purposeful experimentation.
Notable Quote:
"ABX testing... every so often purposely put into their algorithm a very, very different slogan, something left field... It’s teaching them: are they on a good mountain?" — Judah Taub (19:36)
- Nike’s “Just do it” slogan was a real-world X—an unexpected outlier that became a global maximum.
8. Agility vs. Muscle: Adapting in an Uncertain World
[27:32-30:50]
- Those who diversify learning and skills (build agility) are better positioned for unpredictable futures than those who specialize deeply ("build muscle").
- AI progress itself mirrors this trend: newer models have more nodes (agility) as well as more layers (muscle), but agility is increasingly prioritized.
Notable Quote:
"In the world we're entering today... predicting where the future will be is so hard... Prioritizing agility over muscle is just a question we should be asking ourselves.” — Judah Taub (29:50)
9. The True Value of Education & Critical Thinking
[30:55-32:50]
- Bradley and Judah discuss how higher education should refocus on teaching agility, critical thinking, and resilience, rather than rote specialization or outdated career paths (e.g., law school as a default).
10. Community vs. Individual Optimization: Lessons from Israeli Military & Game Theory
[32:50-36:44]
- Judah shares a military training example: Sometimes maximizing group outcomes (the “global maximum”) works better than self-interest.
- This extends into broader societal questions of resilience, cooperation vs. zero-sum thinking, and how crucial community buy-in is for solving collective risks (e.g., nuclear proliferation, AI risks).
Notable Quote:
"A lot of individuals who start playing as part of the team... but slowly, especially towards the end, they start putting more in their own pile... Are you optimizing for your individual score or... for everybody?" — Judah Taub (34:42)
11. Resilience, Collective Good, and Social Cohesion (US & Israel)
[36:48-43:16]
- Israeli resilience is attributed to shared experiences (like military service), which imbue both a sense of solidarity and practical skills for startups and society.
- The US, despite its diversity and equality under law, currently lacks a unifying sense of collective purpose, leading Bradley to express pessimism about buy-in for the common good.
- Discussion of whether diverse, equal societies anywhere have achieved lasting collective cohesion, and what can be done (e.g., mobile voting to push politics toward the mainstream).
Notable Quote:
"We have a society that is multicultural and diverse... pretty much everyone in every way has equal rights under the law... But we don't have a buy in into the collective good that probably did exist..." — Bradley Tusk (41:54)
