The Financial Post reports in its Thursday, Feb. 1, edition that Microsoft, Google's Alphabet and Advanced Micro Devices -- three companies working harder than nearly any other to weave artificial intelligence into their products -- are finding that investor expectations for the technology are hard to meet. A Bloomberg dispatch to the Post reports that all three took pains to highlight progress on AI. In AMD's case, the company predicted that its new AI processors will generate even more sales than expected. Microsoft touted how users were embracing its AI assistants, and Google said the technology was improving its search and cloud-computing services. Investors had bid up shares of the companies to record highs in recent weeks, betting that an AI bonanza would quickly fuel results. What they heard on Tuesday was not enough to satisfy those hopes. Franklin Resources analyst Katrina Dudley said, "Companies are continually having to prove themselves and continually prove the value proposition of AI." Microsoft and Google delivered mostly good news in their reports, but still elicited a ho-hum from investors. Shares of the tech giants slipped in early market trading on Wednesday, the morning after they delivered results.
