AI, mixed reality, and Microsoft Graph have implications for the future of the company's team collaboration platform, Teams. I attended Microsoft Build last month, and bring tales from the future. For Build, an annual conference for software engineers and Web developers, is where Microsoft promotes its products and the tools, techniques, and directions for its third-party ecosystem that have the greatest likelihood of influencing the future. This is especially relevant in the case of Microsoft Teams, given that Teams, unlike Skype for Business, is first and foremost a collaboration solution platform. Three focus areas from Build have implications for the future of Teams: artificial intelligence (AI), mixed reality, and Microsoft Graph.
