This is why research like this is important and needs to keep being published.
What we have seen the last few years is a conscious marketing effort to rebrand everything ML as AI and to use terms like "Reasoning", "Extended Thinking" and others that for many non technical people give the impression that it is doing far more than it is actually doing.
Many of us here can see his research and be like... well yeah we already knew this. But there is a very well funded effort to oversell what these systems can actually do and that is reaching the people that ultimately make the decisions at companies.
So the question is no longer will AI Agents be able to do most white collar work. They can probably fake it well enough to accomplish a few tasks and management will see that. But will the output actually be valuable long term vs short term gains.
