You might be a wee dismissive of how much a developer can do with OpenAI (or the competitors).
I mean there's TTS and some translation stuff that's in there but it's hard to call that "AI" despite using neural networks and the like to solve that problem.
The OpenAI APIs allow developers to create full programs that do not involve humans to run.
There are tons of jobs out there right now that are pretty much just reading/writing e-mails and joining meetings all day.
Are those workers just chat bots?

I'm not sure "doing bullshit busywork more efficiently" leads to better ends; it might just lead to more bullshit busywork.
Interfacing with people and understanding business domain knowledge is in fact something we can do with LLM's. There are countless business domains/job areas that fall into the shape I described above, enough to keep engineers busy for a real long time. There are other problem shapes that we can attack with these LLM's as well, such as deep analysis on areas where it can recommend process improvements (six sigma kinds of things). Process improvement, some might say, gets closer to the kinds of things Graeber might call bullshit jobs, though...
I may just be less of a techno optimist. If history is any guide, the automation of front-line human interfaces will lead to less good customer service in the name of lowering labor cost as a means of increasing profits. That seems to make things worse for everyone except shareholders. In those cases, we’re not making the customers experience more efficient, we’re making the development of profit more efficient at the cost of customer experience.
