EY launched its customized generative AI platform a year ago — at a cost of $1.4 billion — and the technology is already being used by 96% of its employees.

The cost is astounding, but the depth and breadth of use by E&Y, and implications for all professionals and business entities eye-opening. iRobot is not here yet, but it's peeking around the corner. I just sat through a continuing legal education presentation about the ethics of AI, and it is scary.
