The opposite is more interesting, (and the author points it out too). SOTA agents can help run small experiments and help you do the writeup. Should you publish it? I'd personally want to keep a human at least partially in the loop, or have very solid checkers. But for one off personal research it's at the same point as one off personal code: make sure you have a way to test what's valid; but if you do, it often Just Works(tm) Now.
Part of the equation you’re missing is that a human is always in the loop, after you publish.
If you don’t rigorously verify everything by hand before then, you are telling the world that they must do what you should have done for you. Or more likely, you are telling the world that that you expect free intellectual labor and will be ignored and chastised- and cause more scrutiny to fall upon others who did the work properly.
