Entertainment aside, getting rid of CNNs for real-world AI deployment is almost impossible. Even if you went for a ViT architecture, you must process the input using local patches with shared weights for efficiency and generalization. It is even more the case for processing multiple frames at a video level, like in Tesla FSD.
AI is not some sort of natural phenomenon that will just emerge and become dangerous.
*WE* design it and *WE* build it.
I can imagine thousands of scenarios where a turbojet goes terribly wrong.
Yet we managed to make turbojets insanely reliable before deploying them widely.
The question is similar for AI:
"do we think there exists at least one design of an AI system that is simultaneously safe/controllable, and can fulfill objectives in more intelligent ways than humans ?"
If the answer is yes, we'll be fine.
If the answer is no, we won't build it.
Right now, we don't even have a hint of a design of a human-level intelligent system.
So it's too early to worry about it.
And it's way too early to regulate it to prevent "existential risk."
