I've seen companies including my own pouring lots of money into AI. Outside of "replacing developers", I am genuinely curious what have people done that's actually useful?

We've got a sort of "business intelligence" AI they poured a lot of time and money into, and I don't think anyone really uses it because it makes stuff up.

I'm sure there are things. I just haven't seen them. I would love to hear concrete examples.

The cynic in me says I wouldn't want something with the error aptitude and truth telling of a small child taking any sort of important action on my behalf.

Two use cases with my corpo are:

1) Enhanced User guides/manuals.

We sell some very complicated and expensive instruments. As such, making them work is quite hard. One of our biggest expenses is our engineers that go out, physically, to help customers. Company policy is that the first visit is always free. These customers can be very remote (Deep sea oil platforms, Australian outback, quite nice ski country ;) , etc). Often their issue is simple but they can also be very complex. We have phone trees, email, texts, iridium phones, etc. to talk customers through things to avoid these first visits and then hep them afterwards. So adding in AI chatbots is a natural way to help out. People don't feel quite the same 'shame' in asking really dumb questions to a chatbot that they do to a real person. So, to make these chatbots smarter, we use some of this AI mumbo-jumbo (RAG), to help them out. So far, it seems successful and the customer and engineers like the enhanced/AI manuals.

2) Making said manuals

We support 35 languages and many regulatory environments. Our instruments are all compliant with whatever version of a government agency you've got (modulo a lot of time, money, ITAR regulations). As such, making all that paper (manuals, compliance docs, contracts, etc) takes a lot of time and effort and has to pass the legal tests too. So AI is really helpful with it. Most of the work for these large stacks of paper is essentially boilerplate, but all subtly different so that literal copy-pasting doesn't get you quite that far. AI systems have been able to, last I checked, get that team about 5x faster, as it cuts out ~85% of the process and drudgery. Since these documents get hauled into courts, they can't just be blindly AI made, and a human always has to go over everything with a sharp eye still, but AI helps out there a bit too. Last lunch I had with them, they were saying that they were actually working on their burn-down charts now and not just going from panic to panic. As in, they could actually do their jobs.

We had a lack of (digital images of) training cases in emergency surgery. You’d prefer to give ML experience with many rare cases, but must resort to style transfer. Humans can do this, but variously problematic and you’re taking them away from necessary work.
