The American tech giants are being challenged by a powerful new A.I. model from China called DeepSeek. This shows that when there isn't enough competition, our tech industry becomes vulnerable to its rivals from other countries. The American tech giants have a lot of money and resources, but they are still at risk of falling behind in innovation. They have focused on buying out rivals and building barriers around their businesses instead of inventing new technologies. This could affect America's power in the world. It's important to encourage competition and innovation to keep America strong in the future.
