The kwown argument that <<you're already a cyborg>> seems to fit nicely with the current status of humanity. The problem I see lies when you decide to integrate these machine learning models (not "sentient" AIs) as part of neural substrate at a convinient broader bandwidth. We are already seen the disasters of biases, filter bubbles and many more to come. There is a huge gap between a cyborg (or Augmented human) and an AGI. The latter doesn't exist yet but we are slowly building it through the links of our mind. That is both the real summoning the demon and quantum leap of faith in evolution.
