The Time Is Ripe

Eric Drexler at Metamodern has a post about molecular modeling and systems engineering -- and the great potential these hold. "The state of the art in molecular fabrication would enable us to build amazing nanosystems, if only we could design them," he writes. "Rich opportunities are emerging from the convergence of protein engineering, structural DNA nanotechnology, and the advances that have in recent years produced a vast range of nanoscale, non-biomolecular components. ...
