It'd be worthwhile for recreation, but software is kind of unique in eschewing credentials in favor of experience and ability. Civil engineers must be accredited to practice. While I don't think the requirements are as rigid for mechanical engineers, I expect a greater proportion of mechanical engineering jobs have a degree as a hard requirement than in software. This probably leads to less interest in things like teachyourselfmeche.com
I wonder if there are hard requirements for some areas of programming and not for others? There's no reason to require credentials for writing a game because if it fails, try again. But if a bridge fails that's a big deal. So for high consequence software like heart pacemakers or aircraft controls, are there people writing code without degrees?
I don't write aircraft controls are pacemakers, but I know people in the medical device industry, and my understanding is that there are regulatory requirements for the product more than the creators. That said, I imagine those industries are more conservative and credential based. Again, my contacts in the medical industry say that its very academic-adjacent environment (which is very credential-obsessed).
