If we assume more people move to curation bots
Curation bots is too generic to reach any conclusion. It depends how those bots are programmed, what inputs they receive, etc.
We can reason based on economic incentives and those incentives apply equally to humans and bots (created by humans based on the incentives). We can say with near certainty that changing the incentives will change the behavior. It is more difficult to predict exactly how the behavior will change, but we can still make some educated guesses (and accept that despite doing so we will sometimes be wrong).
Agreed. If more people move to curation for the rewards then it's feasible more people will move to curation bots. There are a lot of people in financially struggling areas posting multiple times a day, trying to scrape some rewards together. It's feasible to consider a good portion of them will instead curate content for rewards and, hopefully, hook up with SP holders to help curate for them. Maybe tools like https://wise.vote/ will help as well. I did an interview with Noisy a while back about Wise. More tools like that could bring the perfect balance of human automation and incentive / reward sharing.
Was not aware of wise but think you for pointing out it. That looks great and there can be all sorts of tools for different curation models including delegation, collaboration, and human-machine hybrids. Excellent points.
