Did you read the post ?  The purpose would be to give humans a better chance at competing with bots.  The captchas would be so infrequent that they wouldn't disable the bots and the incentives are for both curation rewards and distributing author rewards to your preferred authors - the bots have the advantage of both since they don't require living like people do.

I agree with this statement. For instance, myself (just to pick an example I know), use a bot to automatically upvote people I trust, follow and like (and always before the 30 minute mark). Usually, I am reading their post, but on a second stage. On top of that, I manually curate many posts (actually a good half of my curation is manual). As a result, this also allows me to vote all over the day, which is better to get my voting power rather high all day long. I cannot believe I am the only one acting that way. 

I would prefer trying to find a 'solution' (is there really any problem with automatic curation?) in the reverse way: anyone who is manually curate get something back. This being said, I cannot think about the 'what' and 'how'.
