I have to say I really dislike all these developer-focused publications, with a few notable exceptions. Most of them just write very shallow articles copied almost 1:1 from the official docs, and don't even take care to update their content when stuff changes. I just don't get why Google wouldn't hand-curate search results like for the Golang standard library or any popular framework and make sure the official docs land on top of the list.
So, long story short that's definitely an area where ChatGPT will replace Google, if it stays as affordable as it is. Today I e.g. asked it about a decorator-style problem I had in Golang and if there was a solution that could do away with using the "reflect" package and would instead use generics, and sure enough it came up with something that worked brilliantly, tailored exactly to my use case. For me, that is the future of learning about software code (and many other things as well). For publishers probably not so great as people might not go to their sites at all anymore, so I expect a strong upwards trend in anti-automation measures.
