Microsoft chief executive Satya Nadella has revealed the Australian government will be among the first in the world to deploy artificial intelligence "bots" to deal with inquiries from citizens. As the tech giant looks to lead in the new era of cognitive computing, Mr Nadella told a technology developers' conference in Sydney on Wednesday morning that increasingly intelligent technology would allow human-like interaction with complex business systems. Mr Nadella told The Australian Financial Review after the speech that the Department of Human Services had completed the largest deployment of the Windows 10 operating system in the Asia-Pacific region and was now working on AI-powered applications. He said the DHS was working to create a smart software-driven conversational bot, which could help in reducing the amount of time citizens had to wait to speak to human staff.
