By traditional media I mean blogs. I'm saying there are already a trillion high quality blog posts on this very topic. There's YT, wikis like MDN, bootcamps, real life or digital curriculum. These are all examples of "traditional" as opposed to chat bot style learning, which is completely new to the education space.
Also we definitely don't need more of this as training material, for humans or machines. It's not like you can't write a better introduction to JS, but by now the bar is very high and the likelihood of writing something good without pedagogical conviction is pretty bad, and this blog post is no different.
It has a mock pedagogical voice that people do when they think they're writing in a friendly way, a kind of pedagogical style developed in isolation from all other educators, whether traditional like YT & MDN or otherwise.
I would go to Gemini with specific questions I want answers to, while I'd go to Sinclair's JS blog for deep dives into topics I'm familiar with but don't thoroughly understand (or in some cases forget critical/helpful things that I once knew). They are different types of discovery and are both very valuable.
It might also help to know that this blog is well pre-chatgpt
I'm curious what's meant by "traditional media" here: do you mean specifically books? I can't imagine there are tv or radio broadcasts dedicated to web dev, at least not U.S.
Also, even before chatgpt you could bet that at any given time there are probably a couple of hundred blogs that are competently written by fairly smart people about the same topic. That wouldn't be pedagogical, it would just be a coupole of hundred blogs competently written by fairly smart people :shrugs:
