Developments such as this are of interest and value for seeing trends & directions relative to WITII? (What if the impossible isn't?). While I would not pretend for a moment to understand any of the details of DNA level work, what I do see is how advances in nanotechnology are continuing at an every increasing pace and penetrating new levels of scale. The quote below summed it up nicely for me:
"The advances in DNA nanotechnology keep coming, and many observers are wondering if this will be the path that leads us to the next Industrial Revolution. Only time — and many more experiments — will tell."
Nanoscale: Robot Arm Places Atoms and Molecules With 100% Accuracy
Date Published: January 12, 2010
Until the mid-1990s, the term "nanotechnology" referred to the goal of creating vast arrays of nanoscale assemblers to fabricate useful human-scale products from scratch in an entirely automated process and with atomic precision. Since then, the word has come to mean anything from stain-resistant pants to branches of conventional chemistry — generally anything involving nanoscale objects. But the dream of a new Industrial Revolution based on nanoscale manufacturing has not died, as demonstrated most vividly by the work of NYU professor of chemistry Dr. Nadrian Seeman.
