It also is coming from a long lineage of thought no? For instance, one of the things often thought early in an ML course is the notion that “early layers respond to/generate general information/patterns, and deeper layers respond to/generate more detailed/complex patterns/information.” That is obviously an overly broad and vague statement but it is a useful intuition and can be backed up by doing some various inspection of eg what maximally activates some convolution filters. So already there is a notion that there is some sort of spatial structure to how semantics are processed and represented in a neural network (even if in a totally different context, as in image processing mentioned above), where “spatial” here is used to refer to different regions of the network.

Even more simply, in fact as simple as you can get: with linear regression, the most interpretable model you can get- you have a clear notion that different parameter groups of the model respond to different “concepts” (where a concept is taken to be whatever the variables associated with a given subset of coefficients represent).

In some sense, at least in a high-level/intuitive reading of the new research coming out of Anthropic and OpenAI, I think the current research is just a natural extension of these ideas, albeit in a much more complicated context and massive scale.

Somebody else, please correct me if you think my reading is incorrect!!
