5 min readThe Internet Is Finished: PHP Catastrophe, iPhone Duo Reviews, and SpaceX-Tesla Merger Talks
The most severe PHP vulnerability in over a decade—dubbed "PHP to shell"—went public Wednesday morning, and the Japanese Prime Minister was tweeting about it. Nikesh Arora, CEO of Palo Alto Networks, told the TBPN hosts that his company's scan found 22 million places where the vulnerability persists, and he warned this is just the beginning: "The models that are in the offing that are about to come upon us in the next two to three months already have more capabilities than the ones that are publicly available."
The PHP to Shell Vulnerability
The vulnerability represents a class of problems in how PHP manages a computer's memory. It can be exploited in as little as seconds on smaller systems, allowing hackers to run unauthorized software on any unpatched web server. Security researcher Ryan Austin at Caliph first uncovered the flaws in August with help from GPT-5.6 Sol, one of OpenAI's most advanced models. The class of bugs had been hiding in PHP source code for years—a security researcher had flagged it as a problem area decades earlier, but the flaw had been considered too difficult to exploit and was largely forgotten. AI found a way.

- (35:30) - Nikesh Arora, CEO of cybersecurity company Palo Alto Networks, discusses the severe PHP vulnerability, the urgent need for organizations to patch and protect critical infrastructure, and the likelihood that increasingly powerful AI models will uncover more security flaws. He also examines the risks of autonomous AI agents, the value of open-source models for transparency, and the sustained demand for AI computing infrastructure.
- (57:40) - Aidan Smith discusses the rapid growth of his systems-first AI lab, its billion-dollar Series A, and breakthroughs in GPU optimization through mega-kernel technology. He argues that better algorithms, architectures, and data efficiency could produce more creative, unconventional AI models while expanding automation beyond intellectual work.
- (01:08:05) - Akhil Iyer discusses his journey from the Marine Corps to co-founding Watchtower Labs, an AI defense startup that recently raised $35 million. He explains how its simulation platform helps military planners anticipate logistics and supply-chain disruptions, evaluate numerous scenarios, and make better decisions during conflicts, crises, and competition.
- (01:14:45) - Max Junestrand discusses his role as co-founder and CEO of legal AI platform Legora and the company’s $88 million funding round at a $550 million valuation.
