Active machine learning — an element of technology assisted review — is a disruptive technology, as Maura Grossman and Gordon Cormack observed in the preamble to their Glossary of Technology-Assisted Review. TAR (a.k.a. predictive coding) is not just marketing hype, although most executives in charge of legal software companies wish it were.

Indeed, those executives are clueless in the face of real change. They stand still, or at best, make slow, cautious upgrades. Most seem oblivious of the fact that their once proud companies are rapidly becoming e-discovery BlackBerrys. Their sales staff and experts must be telling them to act, but they do not hear, do not lead. They are empty suits.
