The only thing that died was Google Reader, and that didn't come close to "taking down RSS". Today there are more options for reading and authoring RSS/Atom feeds than there ever were in the past. We've never had this many good apps and services in the RSS/Atom ecosystem.
I think there were some really interesting aspects of Google Reader that I do regret losing. But it's just so weird to hear people say things like "Ahh yes, RSS, that was a very elegant thing, I'm nostalgic for the days when we had that..." It's like being nostalgic for the good old days when the sun used to go up in the morning and come down in the evening. It's still doing that!
