I wouldn't disregard the bots, though. They can be really helpful to push quality content. I mean, when I'm putting 10 or 20 hours into one article, I would like it to be recognized - so a bot can really help, to give it a nice start and to reach a broader audience.
But you are right: in the end quality content will probably stay and rewarded accordingly.
Yeah that's probably the only legit reason to use bots :D
