Actually, I do have an answer to that, despite that I mostly support what you mean.
A. Yes, there is a hysteric and paranoid fear of intelligent robots, and this can easily escalate to violence.
B. A robot may speak in 9-syllable compound words or 50 digits, but if those are beyond the comprehension of a human, the communication is just as fruitless as when the robot is the dumber party. If we want robots and humans to go well together, their comprehension would best be aligned.

Edit: Come to think of it, I have a perfect example: My AI’s language processing eventually required me to add a list of rules to stop it from turning English into semi-Latin and speaking as such.

I don’t think the issue is that chatbots might develop larger vocabularies that would create a communications gap with humans. However, there is great potential for chatbots to accumulate a much larger knowledge base than any single human could possess. But, what will be much harder is for chatbots to achieve any reasonable level of creativity. So, humans probably won’t be intimidated by very knowledgeable chatbots any more than they are intimidated by Wikipedia. But, if chatbots begin to infringe on human creativity - that may present a different situation.

Part of the discussion was regarding the human age limit at which an AI could be compared. I see no reason why we should aim for a human level of intelligence at all. Let’s surpass it!

In that case Steve, by all means

You may apply my example of vocabulary equally to knowledge; differing world views always create difficulty understanding eachother. Geniuses are often misunderstood by ordinary minds, for instance. Yes, the most intimidating will likely be the aspects that humans most cling to as uniquely theirs, such as creativity. My unfortunate task is to drive that notion back until the human ego is replaced by an open mind again.
Remarkably, children have a much more open mind and science has thus declared children to be born geniuses, whose intelligence deminishes as more and more borders are added to their world view.
