Asked about ChatGPT and whether Microsoft viewed such technology as experimental or strategic, its President Brad Smith told Reuters that AI has progressed faster than many predicted.It's going to be extremely important not just for Microsoft's future, but for everyone's future," he said in an interview this week.CarMax Inc (KMX.N), for instance, has used OpenAI through Microsoft's cloud to create thousands of customer review summaries for used cars that it is marketing, a case study on Microsoft's website shows.His London-based company has more than 20,000 customers including Amazon.com Inc (AMZN.O) using its software, which can generate corporate training and product marketing videos, though longer term the goal is AI producing Hollywood-quality content, he said.At the same time, application developers could win out financially if technology like OpenAI's becomes a commodity, said Alan Cowen, chief executive at research startup Hume AI and a former Google researcher."
