Find a case study about the use of AI in a professional field (so NOT education). This could be ways AI has made business better, or a way it has caused problems. 

Should be from a credible source: a news site (NOT satirical), a governmental site, a university, etc. NOT some guy's cousin off Reddit.

Give me a brief summary, and link to the source, and a one-sentence lesson that can be drawn about technical writing from the situation.
