As someone who is just learning Rails [1], I can definitely empathise with the "black magic" comment.

Some of the stuff it does is pretty much voodoo to me at this point. But - it's voodoo that makes me think - even say out loud to myself, sometimes - "wow". I can see how it's amazing that it does what it does with so little code. I can see how this is an enormous benefit to getting a project up and running. I can see how it'll potentially save me hours and hours of configuration.

That's a great benefit, but it comes at the cost of understanding. What exactly is that line of voodoo doing? I dunno. How do I troubleshoot it if it doesn't work? I dunno. Like, I have no idea.

[1]: As the first real "language" I'm trying to actually properly learn, so take my comments in that context. I am not already an experienced coder. I want to be able to knock up little projects, proofs of concept, in a reasonable amount of time. Rails, to me, seems like the framework that will allow me to do that. We'll see.
