Big tech companies like Microsoft and Alphabet are crowing about A.I. as it lays off tens of thousands of workers

At the same time, many of those same tech giants are also plowing resources into artificial intelligence and gushing over its potential to transform the way business gets done. Microsoft, for example, said it would be laying off 10,000 workers in a regulatory filing this week, citing "macroeconomic conditions and changing customer priorities." But CEO Satya Nadella, speaking onstage at Davos this week, told attendees, "A golden age of A.I. is underway and will redefine work as we know it." A few years ago, Microsoft invested $1 billion in OpenAI, the maker of A.I. chatbot ChatGPT. That includes DALL-E, which lets users generate impressive images by simply typing a prompt, as well as ChatGPT, which can deliver well-written answers to all kinds of queries--and could help Microsoft's Bing search engine challenge Google's dominance.
