In an interview with the German-language business paper, Handelsblatt, Microsoft founder-turned-philanthropist Bill Gates said that improvements in artificial intelligence are the "most important" innovation at the moment. Gates said that the applications of generative AI like OpenAI's ChatGPT could improve office efficiency, drafting invoices and letters. Microsoft announced this week that its Bing search engine will be powered in part by ChatGPT AI technology. Google also recently announced Bard, its ChatGPT competitor. Microsoft co-founder Bill Gates thinks AI software like ChatGPT is the most important innovation right now, and could change health care and education for good.
