Crowdsourced and stake-based content discovery and rewarding, also known as Proof-of-Brain, has been proven a failure, at least in its ideal form. It is, however, better than just wasting power like PoW. I think what the network and all its participants have generated in the three years of Steem's existence is much better than entropy which is the only thing PoW leaves in its wake.

At the very least, having been a participant has taught me many lessons about human nature. The difficulty of getting anyone to join has also been an eye opener.

By the way, I don't think bid bots are the crux of the matter. Vote farming is. Bid bots are but one of the many ways to accomplish ROI maximization at the cost of putting in the effort to curate altruistically.

Then again does that matter? I think Steem is still a shitload of fun and the money is vastly better than on any mainstream platform in spite of everything.

What's great about communities is that each community has an opportunity to create their own variant of PoB, some of which may actually work. What I think has the best possibility of working is an app owning the vast majority of stake in a community token and treating content creators like freelancers and keeping other curators in line by negating any abusive voting done by them.
