DeepSeek, this little-known Chinese tech company, has garnered global attention with its artificial intelligence app developed at a fraction of the cost. It seems that low-cost research and development is not the only path to success; it’s all about technological innovation. The sharp decline in U.S. tech stocks may indicate that they have overinvested in their own R&D, overlooking the silent surge from their competitors. It appears that in the battlefield of artificial intelligence, cost-effectiveness is the real deal.
