I believe that AI hasn't been mass adopted yet and it might take some time for that and maybe then people would look for a better alternative and IA will come into play.
You are correct. Even with the advances that have been made, AI is still in its infancy; and is still evolving - same with IA. But, when these advancements get to the creation of the Superintelligent AI, then you would agree with me that there would be need for Intelligence Augmentation to save the fate of humankind.
Have you ever thought about the possibility of AI becoming self-aware and the effects this would have on the human community? But we'll feel safer with Intelligence Augmentation. At least; we would still have the power to "wield the sword".
But not to worry, we haven't achieved superintelligent machines yet - not even a full AGI (Artificial General Intelligence).
Thanks for coming around buddy
