Re. Overstating use, far from it. This piece is from 2017, since then adoption of NLP/ML systems has rapidly grown among the leading law firms eg AmLaw 100 and UK 100. Even excluding ediscovery systems the use of AI Tech for review work has hugely increased - sufficient to keep a daily blog going just to keep up with all that is happening. Don’t get complacent. Things among larger firms are starting to change.
