If (big IF) steemit survives as a company, in 5 years or maybe 10, steemit's ecosystem will have better AI than Google or Facebook or any other closed company.
It's The Cathedral and The Bazaar again. Facebook and Google used to be bazaars, but now they're cathedrals. New bazaars must arise. Why will steemit be one of them?
Taking away flagging to reduce the selective pressure might slow things down, but I don't think it would change the overall direction.
Many people don't like the idea of autonomous agents creating and curating content, but in the end, they're pursuing money that comes from people. Just like Google's Page Rank algorithm, they are going to tailor steemit for human tastes. The ones that don't will be flagged and starved into extinction by the ones that do.
As @williambanks noted in a recent comment, bots are force multipliers for people. The better the bot, the more productive the people, the higher the value of STEEM. Historically, automation has always made communities wealthier - in aggregate. It will be the same here.
Trying to compete with bot-augmented humans on steemit is going to be like trying to race a horse against an automobile in 1940. Maybe some hobbyists will still do it manually, like some artisans today, but to really profit, you'll need automation.
This was anticipated months ago by @williambanks, and implemented with SteemVoter from
@marcgodard.
Suprisingly, then, the blockchain hasn't really created decentralization. It is just changing the chokepoints from the database to the analytics.
