Sorry, I wasn't clear enough. I'm saying that for most problems, a lot of the relevant data is not digital. I'm a software developer, and most of the time, the task is to transcript some real world process to a digital equivalent. But most of the time, you lose the richness of interactions to gain repeatability, correctness, speed,...
So what people bothers writing down are just a pale reflection of what has been, the reader has to relies on his experience and imagination to recreate it. If we take drawing for example, you may read all the books on the subject, you still have to practice to properly internalize that knowledge. Same with music, or even pure science (the axioms you start with are grounded in reality).
I believe LLMs are great at extracting patterns from written text and other forms of notation. They may be even good at translating between them. But as anyone who is polyglot may attest, literal translation is often inadequate because lot of terms are not equivalent. Without experiencing the full semantic meaning of both, you'll always be at risk at being confusing.
With traditional software, we were the ones providing meanings so that different tools can interact with each other (when I click this icon, a page will be printed out). LLMs are mostly translation machines, but with just a thin veneer of syntax rules and terms relationships, but with no actual meaning, because of all the information that they lack.
