It didn't come across that way to me. I suspect familiarity with the topic is to blame here. As I mentioned, it basically went through and gave a short answer to all the first common questions you see in any discussion about a new technology.

What is it? Does it work? Does it actually work in practice? What do you do with it?

For somebody first exposed to the topic, that's kind of the basic starting point. The post kind of directly went from one answer to the next. As I was reading it the post felt pretty natural. But if you already know all that and are instead reading for more detailed knowledge, yeah I can see why that might seem particularly erratic. It was probably kind of like reading a Q&A without any of the Qs.
