I hate to say this but I think bidbots will be on this platform as long as untimely possible and will act as a primary means to boost one's visibility on the platform (sort of like Steem's version of advertisement).
Steemit Inc's version of advertisement, the Promoted Tab failed miserably as it is not at all profitable seeing it burns ones liquid Steem instead of going back to the owner like what the current bidbot system is now doing. Unless Steem develops a better way to advertise posts then bidbots will be in here for the long run whether the majority of people loves it or not.
Other reason why I think bidbots will survive is due to the fact that not everyone in here loves to write, blog and deliver contents to the blockchain. The top 500 highest Steem Account hodlers in this platform are mostly investors. Investors do not waste their time on doing blogs/vlogs or writing exceptional contents. Seeing bidbots have a high return of investment, all they have to do is just to invest on it, sit back and earn passively. They have it easy! :)
So yeah, bidbots will stay on this platform for a loonnng time.
