They've been able to make all kinds of nano-structures with dna for three plus decades now. But, they are all special purpose, one time programs. They'd then have to re-write the hardware so to speak - kind of like rewiring the Eniac. Now, we have a programmable dna-nanomanufacturing ability.
It's still early days, and really, the goal is to go from such soft nanomanufacturing system with wet-dna nanofactories to a more harder material(preferably diamond). It'll be interesting to see how fast they can bootstrap from dna-nanotech to a more robust, hopefully Diamondoid, nano-factory. But, for now, we should see rapid progress of going to indefinitelly higher bit systems.
