"Will the AI work better because it was "pointed" by a Google SWE?"

Usually yes? (vs pointed by a random vibe coder)

Also the more interesting bit to me here is, that you do not find the reference on the page at all, that the person works for google at all (I only found it mentioned in his X account). With the headline I initially thought this was a official google research project, but the blog reads like a personal project.
