So it’s not hard to imagine Barbara coming to the conclusion that Gotham City still needs a digital presence like what the Oracle computer could provide, but still not being entirely willing to trust in artificial intelligence again after Scarecrow was so easily able to spring a trap in “51%.”
And that could easily lead to Barbara becoming Oracle 2.0, to put a human behind the technology who just so happens to be similar to Oracle 1.0 from DC Comics.
Plus, even if Titans isn’t exactly known for the tightness of its writing, introducing and then destroying Oracle in the span of one hour seems like a big waste unless that story isn’t actually finished yet.
