Yes, that seems to be is main argument against Drexler’s vision, though I wonder if he thinks it’s difficult to come up with a design that would be robust, or if the kind of nanotechnology would be difficult to implement since it requires certain conditions such as vacuum close to 0 kelvin, which might be a bit cumbersome even for a superintelligence(?) unless you hang out a lot in space.
