Sucks for them, but the reality is that chatbots are better/easier to learn from than courses and tutorials.

If I had a question about a new library now, I wouldn't google for a tutorial, I'd just ask ChatGPT.

Speaking as someone who never learned well from courses and always preferred documentation and 'just doing it': I wonder how much of this drop is 100% LLM usage by devs vs. devs realizing a lot of video content was just padded out anyway.

The real question is who was still buying this type of book in the last decade or two? What value were they getting out of it? Was it being used as reference or training or what?

out of tutorial hell into another hell...
