A vast majority of the problems I’m asked to solve at work do not have open-source code I can simply copy or discussion forums that already decided the best answer. Enterprise customers rarely put that stuff out there. Even if they did, it doesn’t account for the environment the solution sit in, possible future integrations, off-the-wall requests from the boss, or knowing that internal customer X is going to want some other wacky thing, so we need to make life easy on our future selves.
At best, what I find online are basic day 1 tutorials and proof on concept stuff. None of it could be used in production where we actually need to handle errors and possible failure situations.
Obviously novel problems require novel solutions, but the vast majority of software solutions are remixes of existing methods. I don’t know your work so I may be wrong in this specific case, but there are a vanishingly small number of people pushing forward the envelope of human knowledge on a day-to-day basis.
