Innovation at the Edges

Deep tech is often cultivated by scientific innovation and meaningful engineering innovation. Examples include cleantech, agtech, artificial intelligence, quantum computing, nanotechnology, advanced manufacturing, and biotechnology. Deep technologies are novel and lend themselves to cross disciplinary and cross sectoral approaches that are needed for today’s climate change and regenerative sustainability issues.
