What I don't follow from the article...
It appears as if the j-lens is your mechanism to peer into "j-space", taking an analog to a circuit board, could the j-space be simply a transmission channel and j-lens is a reader you added to read whats passing through?
All the claims about changing the content of j-space changes the output, inserting content into the j-space changing what the output was, all these could still be true without the j-space being a congnitive global workspace where actual cognition is happening.
Or perhaps they aren't claiming that cognition is happening there but that j-space is serving a space for "working memory", I am definitely not sold on this, but will read more into it.
