Well, my son is a meat robot who's constantly ingesting information from a variety of sources including but not limited to youtube. His firmware includes a sophisticated realtime operating system that models reality in a way that allows interaction with the world symbolically. I don't think his solving the |i+1| question was founded in linguistic similarity but instead in a physical model / visualization similarity.

So -- to a large degree "bucket of neurons == bucket of neurons" but the training data is different and the processing model isn't necessarily identical.

I'm not necessarily disagreeing as much as perhaps questioning the size of the neighborhood...
