For over 50 years, the world built every major technological breakthrough on one assumption: silicon chips would keep getting faster.
That assumption may no longer be true.
In this video, we explore China’s Taichi photonic processor—a groundbreaking optical computing chip developed by researchers at Tsinghua University that performs AI computations using light instead of electricity. If this technology scales, it could dramatically reduce power consumption, overcome the physical limits of silicon, and fundamentally change the future of artificial intelligence and semiconductor manufacturing.
Is this the beginning of the post-silicon era?
We’ll examine the engineering, the physics, the published research, and the geopolitical implications behind one of the most important computing breakthroughs of the decade.
In this video you’ll learn:
• Why Moore’s Law is slowing down
• The physics limits of silicon transistors
• Why electrons generate heat—and why light doesn’t
• How photonic computing actually works
• The role of Mach-Zehnder interferometers in optical processors
• How phase-change memory (GST) allows light to store information
• Why the Taichi chip is hundreds of times more energy efficient for AI inference
• How China built a coordinated national photonics program
• What this means for NVIDIA, TSMC, Intel, AMD, and the future of AI hardware
• Whether optical computing could replace traditional silicon chips
Topics covered:
• Taichi Photonic Processor
• Tsinghua University
• Zhejiang University
• Optical Computing
• Photonic AI Chips
• Silicon vs Photonics
• AI Accelerators
• Moore’s Law
• Semiconductors
• NVIDIA H100
• Integrated Photonics
• Mach-Zehnder Interferometers
• Phase-Change Memory (GST)
• Artificial Intelligence
• Future Computing
• China Technology
The next computing revolution may not come from making transistors smaller.
It may come from eliminating transistors altogether.
