Yes, although Baars' "Global Workspace Theory" (pertaining to the human brain and consciousness) is really irrelevant here. Anthropic only refer to it because they want, as usual, to make grandiose claims and want you to believe that LLMs may be conscious (while of course not being willing to commit to an actual definition of consciousness).
Of course Baar's theater (not ocean) metapor is central to his theory of consciousness which he compares to a spotlight in a theater drawing attention to some players on stage while ignoring others.
OK, so if you strip away Anthropic's poorly applied comparison to Baars' GWT, and appeal to you to believe that LLMs may be conscious, then what are we left with? What is the actual technical content of their blog post (which the Slashdot story doesn't even bother to link)?

Their title "Verbalizable Representations Form a Global Workspace in Language Models" cuts to the heart of it.
The "Workspace" that Anthropic are referring to (fig 2) is just the the activations of the middle layers of a Transformer which is where most of the high level pattern recognition and prediction occurs (since the input/output layers need to convert word sequences to/from these richer middle layer embeddings).
OK, so why call it a GLOBAL workspace (which is central to their grandiose brain analogy)? A: Because the diagram of a Transformer you are likely familiar with puts all the focus on the stacked Transformer blocks with their attention and feed-forward components, and presents the residual connections as more of a technicality (maybe you think of these as just to help gradiant
propagation as in a ResNet). In fact the residual connections are really central to a Transformer, which may be better thought of as an embedding highway (the "residual" connections) passing thought the layers, with the job of each layer being to incrementally augment these embeddings by adding data to them (derived from attention and feed-forward blocks).
So, what makes these middle layer "workspace" activations (i.e. embeddings) global is that the residual highway interconnects all layers and anything added in lower layers will therefore be globally accessible to all layers above it.
So, there you have it: Surprise surprise (NOT) Transformers share embedding values across layers (woo hoo - global) which represent high level concepts, some of which (depending on random output token selection) may manifest in the output, and others just representing internal abstractions and output paths not taken.
