Reading the article, the conclusions seem to line up with what I experience. Namely the part where it says that individual users found a productivity boost.
At my company, we have a bunch of AI based tools set up, and it's impressive how much of the time consuming, boring, burnout-inducing gruntwork I can offload to the robots, and instead spend more of my working hours working on things I actually want to work on.
And we also deploy things like AI search for internal knowledge bases. Being able to quickly get the information you need to complete your job, especially if that information is related to sales is definitely good for business, but I'm not even sure how you'd measure that in terms of "profit".
It is if you are trying to fulfil the requirements from 2 comments above.
