"Please don't sneer, including at the rest of the community." (https://news.ycombinator.com/newsguidelines.html) It's reliably a marker of bad comments and worse threads.

If you know more than others, that's great! but in that case please share some of what you know so the rest of us can learn. Here, for example, it could be possible to add related facts about networking, other ways of connecting computers, obscure details, war stories, bits of history - who knows? All such things could make the discussion more interesting and fun.

(Edit: here's a great example of what I mean. This comment is currently at the top of the thread, which is what we want here: https://news.ycombinator.com/item?id=49506392.)
