You know... this did pretty effectively squash desktop manufacturing... and that was one genie the corps would have loved to see back in the bottle. I really don't see them 'fixing' nanotech and letting the genie back out again - and as to dissonant... well, I seem to recall the last time the technomancers did something big with dissonance, they tried to decommission a certain very old, extremely skilled Decker, and the Sybil virus has hit that decker pretty hard.
On the other hand, I suspect this has quite a lot to do with AIs that want a flesh and blood body; if an AI has the resources, cloning'd be the way to go, but not all AI have that far of a reach... and a clone has no real connections. It also takes time to properly develop a clone - fast growing results in mental disabilities AKA defective hardware, and I suspect this is all about hijacking some wetware on the AI's parts.
