Pretty interesting to think about how the internet has changed engineering. Eg if most things were learned by book in the past, I’d guess that would result in more coalescence around the standard libraries — need enough readership to make it worth writing a book on it, and it’s also easiest to find the books that are most widely available. Now that we have internet and can easily find stack overflow pages, it probably leads to package proliferation, and less solid knowledge of the standard libraries.
