The biggest and least controversial thing will be when anthropic create a onedrive/googledrive integration that lets white collar employees create, edit, and export word documents into pdfs, referring to other files in the folder. This alone will increase average white paper employee productivity by 100x and lead to the most job displacement.
For instance: Here is an email from my manager at 1pm today. Open the policy document he is referring to, create a new version, and add the changes he wants. refer to the entire codebase (our company onedrive/google drive/dropbox whatever) to make sure it is contextually correct.
>Sure, here is the document for your review
Great, reply back to manager with attachment linked to OneDrive
Your example actually perfectly describes why it won't displace anyone.
The user still has to be in the loop to instruct the LLM every time, and the tiniest nuances in each execution of that work still matters. If it didn't we'd have replaced people with bash scripts many decades ago. When we've tried to do that, the maintenance of those scripts became a game of whack-a-mole that never ended and they're eventually abandoned. I think sometimes people forget how ineffective most software is even when written as good as it can be. LLMs don't unlock any new abilities there.
What this actually does is make people more available for meeting time. Productivity doesn't budge at all. :)
In other words, the "busy work" has always been faster to do than the decision making, and if someone has meetings to attend they don't strictly do busy work.
Maybe the more interesting outcome is that with the increased meeting time comes much deeper drinks of the kool-aid, and businesses become more cultish than they already are. That to me sounds far more sinister than kicking people out onto the curb. Employees become "agents of change" through the money and influence they're given. They might actually hire more :D
