Thx for a really informative post, I think the issue with bots as humanoids are already very real! But I like to compare it to GMO, at first it seems like we are doing ourselves a big favor, but give it 10 years and we will be stuck with an inferior product. (Jackass bots, propaganding bots etc.) so I think eventually there will be a need to label all not posts and interactions as excavtly that a BOT!
The problem is that we may never have the ability to fingerprint them in time. They will be untestable to our average minds.
Indeed, This is why we all grow more skeptical to "everything" which in turn actually leads some people to disregard pretty pure science, because when you start to have disbelief in the system, then it is also easy to disregard what helps us live longer, use resources more efficient, and actually enables the western situation where we have time to question everything. And the knowledge that it all can be wrong/a mistake.
I am sorry for a late and clumsy response, but I hope you get the meaning of what I am trying to express.
