Earlier quoted context omitted.
From the article: "We currently don't understand how to make sense of the neural activity within language models." "Unlike with most human creations, we don’t really understand the inner workings of neural networks." "The [..] networks are not well understood and cannot be easily decomposed into identifiable parts" "[..] the neural activations inside a language model activate with unpredictable patterns, seemingly re…
I read this as "we have not built up tools / math to understand neural networks as they are new and exciting" and not as "neural networks are magical and complex and not understandable because we are meddling with something we cannot control". A good example would be planes - it took a long while to develop mathematical models that could be used to model behavior. Meanwhile practical experimentation developed decent…
TFA is about making a tiny bit of progress towards such models. Perhaps you should read it.
