As a CEO, where should we start with AI, and what are the highest-value use cases?

Why AI sounds confident when it's wrong (and how to catch it)
Lawyers keep getting sanctioned for filing briefs full of court cases that don't exist. The AI didn't flag a single one. It wrote them the way it writes everything: fluent, specific, and dead sure.
