Policymakers and scholars must begin thinking about how constitutional principles are being tested by technological change and how to ensure that those principles can be preserved without hindering technological progress. Constitution 3.0, a product of the Brookings Institution’s landmark Future of the Constitution program, presents an invaluable roadmap for responding to the challenge of adapting our constitutional values to future technological developments.
