Copper vs Fiber: Practical Impact on AI Scaling

This Week in AI, JCal sits down with three CEOs building the infrastructure, intelligence, and interfaces for the next era of AI: Jeremy Fraenkel (CEO, Fundamental), Victor Riparbelli (CEO, Synthesia), and Nick Harris (CEO, Lightmatter). We break down what's actually happening beneath the AI hype: the data modality LLMs completely missed, why copper is the real bottleneck in AI data centers, OpenAI shutting down Sora, the build vs. buy debate for AI tools, and how close we really are to AGI.

• AI's Biggest Blind Spot, Tabular Data: LLMs transformed text, images, and code, but 70-80% of enterprise data lives in rows and columns.
• Copper Can't Keep Up: Nick explains why AI data centers are hitting a wall. GPUs compute faster than they can communicate. Lightmatter's photonic chips push 1.6 terabits per fiber and can 3x training speed.
• Why OpenAI Killed Sora & Anthropic's Focus is Winning: Victor breaks down why even OpenAI had to learn the lesson of focus, and why Claude Code has every founder talking.
• Vibe Coding Your Own CRM vs. Buying Salesforce: Jeremy reveals Fundamental built their own internal CRM using vibe coding. The panel debates when building beats buying and when it's a distraction.
• The Omnipresent CEO: Jason shares how he's using AI agents for root access to Slack, Gmail, and Notion, resurrecting former employees as AI personas, automating SDR workflows, and summarizing employee inboxes while they're on vacation.
• Are We Already at AGI?: Nick says the rate of progress is a double exponential. Jeremy argues AGI is a moving goalpost. Victor warns of "Future Shock" and societal disruption.
