Microsoft is moving GitHub even more closely into its CoreAI team, following the resignation of GitHub CEO Thomas Dohmke today. After nearly four years as CEO, Dohmke is leaving GitHub to “become a startup founder again,” and pursue opportunities outside of Microsoft and GitHub.

Part of Dohmke's legacy will be GitHub Copilot, which currently has 20 million users. The CEO discussed how GitHub Copilot has evolved "from a simple, but magical autocompletion tool to conversational coding with Copilot Chat & Voice."

Thomas Dohmke is calling it quits as GitHub’s CEO after nearly four years at the helm, marking a significant shift in how Microsoft manages one of its most valuable acquisitions. The departure signals Microsoft’s push to bring GitHub even closer to its artificial intelligence ambitions.
