Maybe it failed in the consumer app space because it couldn’t keep up with user experience expectations. But if that is the metric, then Matrix already failed too, right?

One new server + consumer app combo could revive XMPP for consumers quite easily.

So not keeping up to users expectations - no matter how much - makes a failure?

I think your argumentation is flawed. If your server+consumer app combo can do that, do that

I was giving the person above me the benefit of the doubt. I assume that was their argument, not mine. But i entertained the idea regardless.
