I don't remember the exact dialogue, but the precursor quest ends with you assembling him and the tinkerer you were working for being shunned by his master as being skilless, etc and the precursor being called a piece of junk and you are given him. Does the apostle see precursor era fabricant technology as a form of technology that is something bad? I am surprised the master didn't see it as a reminder of the past accomplishments of seht and it is interesting that the precursor era fabricants show emotion while the newer current era models don't.
