I don't know about you, but I would rather pay some money for a course written thoughtfully by an actual human than waste my time trying to process AI-generated slop, even if it's free. Of course, programming language courses might seem outdated if you can just "fake it til you make it" by asking an LLM everytime you face a problem, but doing that won't actually lead to "making it", i.e. developing a deeper understanding of the programming environment you're working with.
The answer is "the highest-ranked free one in a Google Search".
Actually, I already prefer AI to static training materials these days. But instead of looking for a static training material, I treated it like a coach.
Recently I had to learn SPARQL. What I did is I created an MCP server to connect it to a graph database with SPARQL support, and then I asked the AI: "Can you teach me how to do this? How would I do this in SQL? How would I do it with SPARQL?" And then it would show me.
With examples of how to use something, it really helps that you can ask questions about what you want to know at that moment, instead of just following a static tutorial.
But what if the AI generated course was actually good, maybe even better than the human generated course? Which one would you pick then?
