What is much more likely than them going through the hassle of trying to make those bastards is that they will ultimately. Draw from the knowledge gained in their development to produce another distinctly human tech. Even then, the volume of material entering the archive is tremendous. Every single… everything… in a civilization of well over a trillion sophonts pours in on a constant basis in addition to everything they can get from everywhere else. Simply updating them all requires significant resources and still, there are inconsistencies.

They lose The Locus and they lose the “Grand K” of their archive and that’s before we even start to address the rumors that not everything in The Locus is released to the official backups.
