In the video, the speaker discusses the evolution and future of computing technology, focusing on the emergence of light-based computing, particularly through the innovations of photonic chips. As the demand for computing power continues to rise, traditional electronic chips are struggling to keep pace due to limitations in speed and scalability. The speaker introduces a new class of chips known as Native Processing Units (NPUs), which utilize light instead of electricity for calculations, significantly increasing computational efficiency and density. The discussion also highlights the technological advancements made by Q.ANT, which has developed a fully functional commercial light-based computer that employs lithium niobate—a material crucial for minimizing light loss during computations. The video emphasizes the potential of photonic computing to outperform traditional GPUs, particularly in AI applications, while also addressing the challenges of controlling light and the implications of integrating photonic systems into existing computing architectures. Finally, the speaker suggests that the future of computing will likely consist of a combination of various technologies, including analog photonic, digital, probabilistic, and quantum computing, each serving specific applications.
