That might explain why so many people learning a novel programming language start, but nearly never finish, writing a book or tutorial about it. For example, there are far more incomplete Common Lisp tutorials than there are working / fleshed out code examples on GitHub. The endless unfinished tutorials and "books" are suspiciously similar, and nearly always give up at the same not-yet-practical level. The same goes for other technical subjects. Raspberry Pi is another area where you can find different versions of nearly the exact same incomplete tutorials everywhere.
