this article seems to take it on faith that neurons are aeasily findable, even if their meaning is tricky to untangle: it would be sharply improved by description of how the neurons are being isolated before the meat of the article, the naming of the neurons, is performed. In particular axis aligned semantic directions are incompatible with the classic superposition description, where the meaningful directions are nearly orthogonal, allowing many more to be packed onto the sphere than it has dimensions. (i’m also aware of work showing that Adam or relu pushes semantics onto the axes, but it’s not clear that that’s what he thinks is happening)
