a Reddit thread on r/Futurology that discusses a new photonic AI chip developed in China called Taichi-II. The chip operates using photons, or light particles, and is claimed to be a million times more efficient than its predecessor in low-light conditions. This innovation could lead to significant advances in AI and potentially even artificial general intelligence (AGI), but the comments section of the thread expresses a wide range of opinions on the topic, from excitement and optimism to skepticism and concern about the ethical implications of such technology. The thread also delves into discussions on the state of AI development in China, the potential for AI to be used for malicious purposes, and the nature of capitalism and socialism.
