Vivek is leaving his position as chief information officer of the whole USA after making major contributions to the country.

The deal is that it’s hard to get stuff done in Washington, with lots of entrenched interests, and sometimes projects that don’t get done, or worse, get done and make things worse.

Vivek both helped get projects done and helped slash other projects, savings billions of dollars in the short term and enabling a lot of other good projects.

The country needs him, and he’ll continue to serve as a joint fellow at the Kennedy School and the Berkman Center for Internet and Society. (Both groups do really good work for the world.)
