What you're saying essentially is that the only times digestion of input would benefit from the things Bret Victor talks about is when those inputs are others' output. It seems that this suggestion would have only come from someone who finds themselves dealing almost entirely with the output of others and trying to make sense of it, rather than any original research or thought. What's more, is that I feel like I'm in some sort of Escherian loop here, because to anyone for whom is the case, they'd never have been interested in trying to make the suggestion that these tools wouldn't necessarily help elsewhere (having no "elsewhere" to contrast it to.)

The types of tools Bret focuses on are as important if not moreso for solo endeavors of research/discovery/understanding as they are for trying to achieve person-to-person communication with the smallest possible time-to-understanding penalty.

Indeed. More to the point, what I'm implying is similar to the Allegory of the Cave. Thoughts are not constrained by time, space, or physics. I can build whatever structures in my mind, create, theorize, hypothesize, but if I can't communicate that to others, what have I done? Navel gazing I wager. Example, Einstein was really good at communicating his ideas thru writing and mathematics. But whatever one communicates is a projection, a shadow on the wall of the real content of the thoughts within. The point being physical media of any sort is a poor substitute for the canvas of the mind.

Most of the types of tools being discussed here are ones to help with the first part. Not being able to communicate something after having figured it out is an appreciable problem, but not being able to satisfy the preconditions—of having figured it out for oneself to begin with—has necessarily at least as many negative consequences.

As for the question, there exist plenty of contexts where a realistic answer would be "quite a lot". There are lots of engineering problems that fit in here. It doesn't matter that you're able to communicate to someone the novel discovery you made that went into the implementation of the software they're using. That the software/bridge/ag technique/etc simply exists comes packed with benefits all on its own.

This isn't even to mention that, in regards to communicating to others something that you've worked out for yourself, the tools that you would have used to do that work initially (e.g., visualizations) are apt not to be described for that purpose as "completely useless".
