Cerebras just had the biggest US tech IPO since Snowflake — 2026-05-17

## Short Segments A student with a laptop and a radio halted four high-speed trains in Taiwan, exposing a 19-year-old security flaw. We'll also cover how GM, Ford, and Stellantis are cutting white-collar jobs as AI reshapes the auto industry, and Samsung's last-ditch talks to avert a major chip factory strike. Coming up, we'll dive into Cerebras' record-breaking IPO and what it signals for the tech market. In Taiwan, a university student disrupted the high-speed rail network using a laptop and radio, exploiting unchanged crypto keys from 19 years ago. The student transmitted a falsified General Alarm signal, causing four trains to switch to manual braking and halting the network for 48 minutes. This incident has prompted the Ministry of Transportation and Communications to review and harden the security of railway systems. The breach highlights the critical need for updated security protocols in infrastructure systems, especially those relying on outdated technology. GM, Ford, and Stellantis have cut 20,000 white-collar jobs, and AI is set to accelerate this trend. The "Detroit Three" automakers have reduced their combined white-collar workforce by 19% since their recent employment peaks. This week, GM laid off between 500 and 600 IT workers while hiring for 250 AI roles. As AI technology advances, it is reshaping the workforce landscape, prompting automakers to prioritize roles that align with new technological demands. This shift underscores the growing influence of AI in the automotive industry and its impact on employment. Samsung and its union are meeting in a last attempt to prevent an 18-day chip factory strike. The negotiations, described as the "last chance" by South Korea's Prime Minister, aim to resolve disputes over performance bonuses. If talks fail, over 50,000 union members are expected to walk out, potentially disrupting operations at the world's largest memory chipmaker. The outcome of these negotiations could significantly impact Samsung's production capabilities and the global chip supply chain. Malta has become the first country to offer every citizen free ChatGPT Plus, with one condition. OpenAI has partnered with the Maltese government to provide this service for one year, contingent on citizens completing an AI literacy course developed by the University of Malta. This initiative aims to enhance AI understanding and accessibility, setting a precedent for how countries might integrate AI education with technology access. The program is expected to scale as more residents complete the course, potentially influencing similar initiatives worldwide. ## Feature Story Cerebras Systems just had the biggest US tech IPO since Snowflake, raising $5.55 billion and closing its first day on the Nasdaq with a market capitalization of approximately $95 billion.
