Well, it is good enough for a huge percentage of what general administrative office staff are doing all day. Essentially copying information between textboxes, slightly rephrasing, clicking buttons, formulating emails to people to send in various documents, scheduling meetings, making reports that are fairly mechanical summaries of other information etc. Not all of it is like this, but probably in the range of 30-70%? Some of it may involve human judgment though, which is harder to automate, like whether some expenses are justified enough etc. But you can just replace those kinds of judgments with more clearly defined rules and cost limits etc.

Have you tried using "computer use" models? They just started to get good in the last few months. They can comfortably use GUIs, click the right buttons, enter the data faster etc. This is very significant and my programmer friends often don't appreciate the earth shattering consequences. The vast majority of software in such applications is legacy stuff or proprietary and does not and likely will never have a programmatic API. The only way to interact with it is via GUI. And an AI working that GUI can be deployed unilaterally by the customer of the software company who made the GUI program. This makes adoption and automation much easier. My prediction is that within 1 year (maybe 2) GUI-using AI will be much more powerful and it will be everywhere (of course it doesn't need to be displayed on a screen, it will do its virtual clicks based on a virtual screen buffer rendering in an isolated virtual machine, along with countless other agents in parallel).

There will be huge controversy around it, because this will be the first instance that regular people will see AI do work that resembles their day job all over social media. There will be panic. There will be new license terms saying only humans are allowed to operate the GUI, and AI use is either forbidden or costs extra. But this will not be checkable properly. Even when forbidden, some employees will pay from their own pockets to have cheap AI do the job instead of them.
