It’s not really that complicated. In fact, it’s literally by design easier than the old 90’s “everyone in their own forum” where you literally had to sign up to each and every place to have a voice or a vote; now, you only need to sign-up to at best one instance.

In fact, I’d say much of the complains about complexity we see nowadays are part of the general appeal to anti-intellectualism that runs rampant on the modern internet. Most things should not be “fire and forget” for good reason, and the social internet, much like driving a car let alone a truck, is a good example why. It’s curious in that sense that you quote this:

As the saying goes, “Society can only move as fast as its slowest member.”

Before mentioning I’ve ever heard this anywhere where there’s decent people, so perhaps it’s something that’s told in KKK circles or the like. Like, this is so sorely and patently false it feels like an attempt at trolling. Society moves past the “slow” members and throws them under the proverbial progress bus all the fucking time. That’s what capitalism, collonnialism and consumerism is all about. A good society has to be slow, because it has to observe, think, evaluate and teach.

There are severe pain points still on the general fediverse experience and in some service / instance particulars. You make good point in mentioning a few of them such as the lack of unified onboarding, better guides (technical and visual) and quite definitively the discoverability problem. But I’d frown at some of the proposed solutions like “smart algorithms”
