Chinese scientists have made a new computer chip that works only with light and doesn't need electricity. This chip is better than a similar chip made by a company called Nvidia because it uses less energy and works better. This new chip can help China make better and faster computers and other devices without needing to buy chips from other countries. Read from source...

- The article claims that the Taichi-II chip surpasses Nvidia's H100 GPU in energy efficiency, but it does not provide a direct comparison or a clear metric to support this claim.
- The article cites the South China Morning Post as a source, but it does not provide a link to the original article or any additional information about the study or the researchers.
- The article mentions that the Taichi-II chip operates entirely on light, but it does not explain how this technology works or what advantages it offers over conventional electronic computers.
- The article states that the Taichi-II chip's performance is superior to its predecessor in various scenarios, but it does not provide any specific examples or data to back up this claim.
- The article discusses the implications of this breakthrough for China's chip industry and its self-reliance efforts, but it does not provide any context or analysis of the broader technological, economic, or geopolitical factors that may influence this development.
- The article ends with a vague statement about China's access to Nvidia's AI chips and their potential impact on the country's technological progress, but it does not explain how this relates to the Taichi-II chip or the optical AI methods that the researchers are developing.

### Final answer: The article is poorly written, lacks credibility, and does not provide enough information or evidence to support its claims. It is not a reliable source of information about the Taichi-II chip or the optical AI methods that the researchers are developing.
