Microsoft will increase its use of artificial intelligence in order to improve the company’s products, chief executive Satya Nadella said when revealing the tech giant’s latest financial results. The company behind the Windows PC software reported revenue of 24.1 billion US dollars in the three months to December 31, up on the 23.8 billion it generated in the same period last year, an increase driven by the firm’s cloud-based products, Mr Nadella said.
