Nah, this is the second part of the industrial revolution. First part replaced and augmented physical abilities so instead of making things by hand we automated away a large portion of the work but not all of it. This is augmentation and automation for intelligence. Yes, a lot of what we currently do "by mind" will be automated but these systems have their limitations. It's still going to be crazy though, imagine what it was like to be the town blacksmith when they first heard of a steam hammer. Nowadays we have very few blacksmiths but we have a lot of people designing parts that will be made on a CNC. What is the role of the human once the labour of clicking away at a mouse hunched over a screen to produce a part is automated? Now we just discuss the end product with the AI, look through some renderings, ask for different versions, ask it to run simulations, tell it to send the file to the CNC? Now that anyone can "design" a part or a whole product by talking to an AI what kind of new jobs does that entail? There might be a big demand for computer controlled production of one off designs. What kind of incredible inventions and wonders can we create now that we can basically conjure our thoughts into existence? There's going to be a whole cross-disciplinary science of combining various areas of human knowledge into new things. Too bad Disney already coined Imagineer.
What you're describing is a cyborg, or a collaboration between man and machine -- something that has arguably been going on at least since a caveman used a stick as a cane.. but it's much more advanced now.
Arguably, a cyborg is no longer fully human, or at least not only human, and as more human faculties are "enhanced" a smaller and smaller portion of the whole remains merely human.
Eventually, the part of the whole which remains human may become vestigial... and then what?
