The trope that software projects are poorly documented is so pervasive as to be saying nothing at this point. Despite extremely useful and celebrated documentation projects (MDN and Python off the top of my head) that dramatically accelerate other peoples' learning and productivity.
But when the topic is raised, the response is always "But we don't have time for documentation".
And when that time is given it becomes "It will be useless or out of date soon anyway, just go read the code" (As if there is nothing between non-practical high-level docs and per-line code comments.)
And when forced it becomes "Fine, but it won't be any good" or "Other people won't read/benefit from it anyway".
And when it's done, often as little effort as possible is put into it.
All of which smell to me like cover stories for: "I just don't want to do it."
Supremely narrow minded. Knowledge has many facets.
In other words: example?
Henry Heimlich used "the heimlich maneuver" for the first time when he was 96 (in 2016), 40 years after inventing it, in the "senior home" where he was staying. But according to you, having invented was nothing in the first 40 years, because he didn't actually use it, never mind that it was used by others and taught as a life saving technique.
You're just beathtakingly ignorant of how progress actually happens. It's like your understanding of the world comes exclusively from thinking about the world in abstract hypotheticals, rather than interacting with it, which is ironic coming from someone stating that only action matters.
If all he did was read books about things other people did, he certainly would not have invented that.
Your following attempt at armchair psychology is humorous, but not much beyond that I’m afraid. Don’t quit your dayjob.
And my specialty is spotting morons on social media.
Do you have a real counter example? Someone that through reading the material of others alone, with no practical/“hands on” experience, was able to develop what you consider “deep” knowledge?
Edit: A day ago you were arguing talent can’t come without training. https://news.ycombinator.com/item?id=39656444
In fact much of your comment history is dedicated to claiming knowledge requires product. How bizzare.
> In fact much of your comment history is dedicated to claiming knowledge requires product.
Your comment is a great example of someone putting their (mis-)interpretation into something.
No, I didn't say anything about products. I leave that for tinkerers and sales people.
> Do you have a real counter example?
Already gave you one, no idea why you're asking again.
^Or at least something with approximately that level of intellectual capacity/honesty.
True “depth” comes from the know-how acquired in digging through all the minutia nobody else though to document, on your way to producing a new creation nobody else thought to build.
