The New Kind of Flesh: "Errors are coming out"

A very awkward locution, tempered only by the direct analogy of errors to night bugs in the line that follows.  Night bugs do come out, seemingly of nowhere.  Errors in general, however, remain hidden or manifest differently.  A thing doesn't work as it was expected to do.  Maybe a message pops up, but that isn't the same thing as the error itself "coming out," is it?  But here, not just a single error, but multiple errors are coming out, like debutantes or celebrities, even as we read.  Errors are becoming manifest, they are coming out from somewhere within, from the place where errors reside before they come out, the locus of potentiality, or of essence.
