TLDR; in my opinion, the interesting question is less what happens at the top firms or to top engineers than what happens as the rest of the world gains access to engineering skills well above the previous floor at a reasonable price point.

For a long time, it was thought that they indeed contained only the latter, but my certainly non-specialist grasp on the matter is that we now know they were used to encode much more than that. In addition to being used directly to verify calculations [0], they contained "histories, laws and ceremonies, and economic accounts" or, as the Spanish testified at the time: "[W]hatever books can tell of histories and laws and ceremonies and accounts of business is all supplied by the quipus so accurately that the result is astonishing"[1]. My---again crude---understanding is this was through embedding categories, names and relational data in addition to numbers, signaled not least through texture and color [2].
I likely come across as if I'm trying to over-inflate the Incan knots, but really it's just to say they appear to be a rather fascinating in-between of legal-administrative inscriptions, whose discovery transformed understanding of Roman institutions over the last century or so, and the straight-forward manuscripts of the Herculaneum.
[0] My elementary and probably out-of-date recollection: an emissary would come to towns with Quipus containing work orders, which would be validated with the community on the spot.

They're comparable in that sense to the Heculaneum manuscripts, which researchers have lately made great progress on with deep learning [1]. I hope an equivalent initiative someday starts on the Quipu.

As someone said below, I suggested figuring it out early is best because of a lot of things that just work differently, especially in learning. There seems to be a real selection bias that most people who learned they were aphantasic reading a New Yorker article, say, by definition figured out how to make it work somewhere along the line. Aphantasia isn’t at all a learning disability in a real sense, but you definitely have to approach things differently.
The connection of aphantasia to strongly deficient autobiographical memory (SDAM) is well-attested now. You can find numerous clinical studies on the matter.
It's hard to write about these things...
That said, it really is binary or not whether you cannot see images at all in your head and there are, in fact, some very real downsides related to episodic memory. As someone who realized I was aphantasic late in life, I think it's pretty important to realize you are if in fact you are---ideally as early in your educational process as possible. For everyone else, it's interesting to realize some people have more vivid imagery than you and some people less, but probably that doesn't change very much about your life.
I find the typical thought experiment of "picture an apple" less illustrative than something like "picture the face of a co-worker you see every day but aren't friends with and tell me the color of their eyes." In the apple case, everyone has a "concept" of apple and an experience of "thinking about an apple"---the difference is really in what you can deduce from that thinking and how, if that make sense. Are you reasoning on the basis of an image or from more or less linguistic facts ("apples are red therefore..." etc)?
The main difference that's more than an "implementation" detail of how you think, so to speak, but really a limit concerns what's called "episodic memory." People with aphantasia rather singularly cannot re-experience the emotions of past experiences. There are a lot of studies on this and I can look up the references if you're interested.
When I was really trying to make sense of my own aphantasia, I found https://www.hurlburt.faculty.unlv.edu/codebook.html to be one of the most fascinating resources: it's essentially a catalog of all the different modalities of inner experience a large study found. Probably there are critiques of his methodology etc, but regardless it's an invaluable aid for trying to figure out how exactly you think.
I haven't looked too much into Deepseek's actual business, but at least Mistral seemed to be positioning themselves as a professional services shop to integrate their own open-weight models, compliant with EU regulations etc, at a huge premium. Any firm that has the SOA open model could do the same and cannibalize OpenAI's B2B business---perhaps even eventually pivoting into B2C---especially if regulations, downtime or security issues make firms more cloud-skeptical with respect to AI. As long as OpenAI can establish and hold the lead for best open-weight/on-premise model, it will be hard for anyone to justify premium pricing so as to generate sufficient cash flow from training their own models.
I can even imagine OpenAI eventually deciding that B2C is so much more valuable to them than B2B that it's worth completely sinking the latter market...
The dreaming question is really fascinating: it doesn’t seem to be impacted in its essence by all the incredibly diverse structures of inner experience. It’s clearly a function of the brain much older than conscious experience [1] and I’ve also read research supporting its necessary role in learning (roughly equivalent to reinforcement learning on synthetic data). There are very rare periods in my life when I’ve remembered my dreams often—-which definitely suggests it’s a skill I could refine—-but generally I recall one or two a year.
One of the interesting questions is which properties of inner experience are genetic, which early developmental, and which skills one can refine at any point in life. Before I knew I was aphantasic, I had a phase studying chess and I tried so hard to “get better” at visualizing games—-one of the most frustrating experiences of my life! Knowing one’s limitations, you can then refine appropriate techniques like algebraic representations etc.
[1] GPT found some terrific papers on this question. In fact, dreaming (measured by two-phase REM sleep cycles) goes back to vertebrates — and seems to have been convergently evolved in insects and cephalopods. Jellyfish appear as the limit with only a single sleep phase. https://www.nature.com/articles/s41586-023-06203-4 is fascinating.
It’s actually something very interesting about the function of dreaming in the brain that this is the case. That there’s such insane variability in the structure of conscious experience and memory, but the imagistic quality of dreaming fulfills a necessary role for all. I’ve read reputable studies that suggest it’s crucial for learning, something similar to training on synthetic data.
I’ve always found it interesting that in programming communities the two extremes of aphantasic and hyperphantasic seem to both be very overrepresented.
