The kind of SNR that causes an attempted takeover? As IRC has depopulated it's been increasingly inhabited by a particular type of person and has a particular culture. That's fine, but ascribing some technical superiority to it because of your cultural preferences doesn't make sense. IRC attracts a certain type of user who persists despite its UX; it's not technologically superior. The rest of us who aren't in that culture go elsewhere, to a network that fulfills our needs. Like Matrix (or even XMPP for some).
