>Why not see if it can assemble a copy of itself -- if you find a genie in a lamp why not ask it for more wishes?

Robots that can build things already exist and can be purchased second hand, but I haven't see this level of hacking them to self replicate. The logistics of getting enough parts, and having the general purpose ability to diagnose a very wide range of issues with used components, and similar seem to prevent this from being some sort of self replicating singularity.

If such a robot did already have the power to do such self replication, why would it wait for a second hand hacker instead of the builder of the robots using them to produce copies at reduce cost?
