On this matter I also do not feel fully qualified to contradict you but I will point out that it will require a very intelligent script to pass itself off as human in words and behaviour.

I also have faith that Steemit wil evolve to incorporate the improvements necessary to make a drastic increase in information flow perfectly managable.

It'll be interesting to see how things develop over time - and I hope that your prediction proves pessimistic. :c) I am warming up to the patform.
