My wife (head of accounting for a small business) has been working on automating large parts of her job using AI.

It's not completely reliable and the human cannot be taken out of the loop, but the number of menial tasks she's been able to automate has been really cool. A lot of processing data that arrives in non-standard formats, generating documents based on that data, etc.

She still has to review everything, but her workload is way down, and when her assistant quit she automated away his whole position.
