In healthcare, engineering, construction, manufacturing, or aviation industires adoption is mostly on the admin side for low priority/busy work - virtually no doctors, pharmacists, nurses, engineers, technicians or even sales people use LLMs on the job. LLMs products have serious quality issues and are decades behind industrial databases, simulation and diagnostic tools.
On the other hand in academics, consulting, publishing, journalism, marketing, advertising, law and insurance industries it's wildly adopted and is surging. For example, Westlaw's Co-counsel is better at drafting and case law briefing than all but the most experienced litigators. Not only it has not replaced lawyers, but is causing a boom in hiring since the time and cost of training new associates is drastically reduced and allows firms to take on more clients with more sophisticated case work.
