The use cases I've seen that actually make a ton of sense to me are anything with rules engines with cumbersome steps or syntax.
It's so much easier to allow input like 'block traffic from outside the US this weekend from the hours of x to y' or 'junk emails that come from a different smtp server than the domain name indicates' and so on.
But sometimes it's annoying to create such rules either due to having to click through multiple screens, or not remembering the exact syntax offhand.
Locally, something like iptables comes to mind. I've used it hundreds of times, but never regularly enough to remember how to write more complex rules without consulting the manual or Google each time.
This would be like writing email filters in gmail or smart playlists in iTunes.
Possibly, you could ask the LLM for the examples and counter-examples that look most likely to be a bug?
If you need to know that the output is perfect then you need to check it, and if you need to check it then maybe it's better to just get an expert to do it in the first place.
Yeah but also maybe an expert gets a shipload more done using an AI? Huge productivity increase? Dunno!
As long as the mad dash translates into healthy 8-hour work days - have fun!
Some of the use cases are certainly of dubious benefit to the actual product.
