Because we don't like uncertainty, and the AI future is uncertain. There are multiple high probability scenarios.
Because we're seeing how its capabilities increase overtime. I find the rate at which I prefer to go to an AI than an UpWorker is scary.
Because we——the people——are not in control of it. We're at the whims of whatever it and the tech bros want (technocracy).

What you mentioned is not a technocracy. Technocracy is when all decisions are made by real specialists in the field, based on scientific methods (simply speaking). What you mentioned is a plutocracy, a form of oligarchy in which decisions are made by people of great wealth.
I couldn’t just ignore this because, in my view, technocracy (as I’ve described it) still has some merit - for instance, appointing only genuine economists to head a hypothetical Ministry of Economy makes some sense - whereas oligarchy and plutocracy have nothing good to offer. Of course, this is just my personal opinion.
