It seems like a stretch to argue that we have any clue what the evolutionary consequences would be for something that's been around only a couple of years. Human-level intelligence took millions of years to evolve even when the lifespans of our ancestors were shorter than they are now, so trying to predict how something so new will affect the biology of future generations seems like it would be pretty much impossible to reason about. Even trying to predict how technology will affect society in a single generation is hard enough, and that's hardly long enough for any noticeable evolutionary changes to our intelligence as a species to become noticeable.
