I think this sounds accurate. And, on the surface, there's nothing wrong with a modernized, glorified IRC network, but it should be obvious to anyone here that this is utterly useless as a store of useful information that can be archived and indexed and searched by others later. It's like two guys sitting next to each other at a bar and striking up a conversation, and one tells the other a great tip he figured out for how to fix a very particular issue with his car. That's nice, but the other guy just got lucky he met someone with this knowledge, and all the other people with that same issue are out of luck and won't learn this valuable nugget of info because there's no record of it anywhere.
IRC wasn't run by a proprietary company that demanded your phone number to read the channels. So discord is basically the exact opposite of IRC (and everything else in the open Internet).
