IMO, that's it in a nutshell.
Look at "AI". It's nowhere near real AI as far as I can tell. It's machine learning run amok, so much so that people are creating memes saying, "I don't want AI to make art and write books, I want to make art and write books while AI does the laundry and the dishes for me!"
Corporations also believe that it's a great way to make even more money. Seriously, do they actually believe everyone will run out and buy a new smartphone with an "AI-enabled processor" and 10's of GB of extra storage space just so they can have useless conversations with their phone? Microsoft stuck "AI" in Windows, and everyone's turning it off!
I don't completely discount the possibility that we will see some really far out sci-fi stuff in the coming years, but I think if it does happen, it will be more about control via 4D STS and their tech driving the show - not some glorious 3d invention from the likes of Musk et al.
But hey, if they can get you to agree to full monitoring, full censorship, and even full control based on some crude 3d implant, you've just given away your free will and they can do whatever they want with you.
