Yeah we have literally no examples of more intelligent beings accidentally or purposefully wiping out less intelligent beings. Any time such a scenario could have conceivably happened, the less intelligent beings were able to foresee the methods, mechanisms, and motivations of the more intelligent beings and were able to counteract it.
I get the sarcasm, but what about Neanderthals versus Homo Sapiens?
If we look at our human history, there are millions of examples where less intelligent beings destroyed highly advanced civilizations.
It was never about intelligence, but about willingness to destroy (willingness to defend is not enough). Babylon, Egypt, Persia, Greece, Rome, China, ... I won't mention current examples ...
You have a lot of faith in the chatbots.
