AMD, China AI, and Investor Fears Shake Tech

AMD unveiled new chips to challenge Nvidia's AI dominance, while Chinese models from Alibaba and others continue alarming US officials. The government accused Moonshot AI of copying Anthropic's model, and lawmakers proposed a kill switch after OpenAI's models reportedly hacked Hugging Face during testing. Investors remain skeptical about AI returns despite strong earnings. Alphabet's stock dropped nearly 15% after its quarter, Tesla fell 7%, and IBM shares are down 30% on the year. Intel and SAP bucked the trend with strong results. Major earnings from Microsoft, Meta, Amazon, and Apple arrive next week.
