"What we are really making are tiny DNA circuit boards that will be used to assemble other components." Greg Wallraff, an IBM scientist
That's right, we're actually moving forward toward designing and implementing an automated system built on DNA.

Adleman had the initial vision of a DNA computer in 1993 (Wired Article) and is now widely credited with being the father of the field.
