On Tuesday in a conversation with Gartner analysts, Satya Nadella talked about the future of AI, the cloud, Windows, and what his company plans to do with LinkedIn. But the most notable remark from Nadella was when he said this, "Windows is the most open platform there is." ZDNet adds: It came in the context of Nadella talking about Microsoft's mission to unite the three big constituencies in the technology world. "That's the approach we've always taken," said Nadella, "bringing users, IT, and developers together... When you bring them together, that's where the magic happens." He reminded the audience of several thousand technology leaders that Microsoft began by making tools, then it made apps, and now it makes platforms. Or, it buys them.
