CryptoWorld News reports that CNBC personality Jim Cramer stated on Wednesday that cloud computing giants must not be stingy with spending on artificial intelligence development. He pointed out that the rise in data centers and AI-related stocks is not a fantasy, but the result of companies actively investing in infrastructure, with customers already in place and cloud service providers working hard to meet these demands. Cramer took Amazon as an example, emphasizing that a comprehensive AI deployment is no longer just a pipe dream, and quoted Amazon's CEO as saying, "If you don't build this stadium, customers will go elsewhere, and you will miss out on a huge business opportunity."
