In a way, transitioning like this, rather than only creating non-human AI in parallel, would hopefully transfer some of our humanity into the machines. In any case we would look back at this transition as a natural metamorphosis. I wouldn't be surprised if this metamorphosis is a natural emergent phenomenon among civilizations across the universe.
I imagine a electrode neural link would with much the same way, but faster and less disruptive. Humans would off load tasks like: information discovery, complex mathematical calculations, and making arrangements for holidays to their AI companion.
Also filter bubbles in media have generally been created by quite basic algorithms that only meet the definition of AI when you really stretch it. You might argue that a more advanced AI might create more toxic bubbles, but it seems to me that our society has just about perfected toxic bubble creation and any further advancements in the field would suffer severely from diminishing returns.
I feel people are vastly under-estimating just how complex general intelligence is. Even simplistic intelligence like what you find in a worm is far beyond us, not to mention insects. Thinking that we could decode human thought out of electrical signals in the brain at this stage of our understanding is like the ancient Greeks thinking they could build a rocket to the moon.
