It is flat out not a nice feeling to experience uncertainty about things like "can I pay for someone to look after my child so I can go to work?" and "will I have food to eat this weekend?". For some people, "will AI mean my job goes away next year?" leads directly to those concrete uncertainties, and they understand that, and that is why they don't enjoy the uncertainty they are currently feeling. I'm guessing that for you, those first two concerns have not come up?

Sure! Uncertainty is a spectrum, and there are certainly moments where it's not a nice feeling. I'm a father, and I'd be lying if I said I haven't had those feelings over the years. My (making it very clear here that one's mileage will obviously vary) approach?

I don't know what's going to happen. Maybe I'll need to figure out childcare, maybe I won't. Maybe I'll have food to eat this weekend, maybe I won't. Maybe my job will go away next year, maybe it won't. Today, there's work, and I'll do that work as best I can. Today, there's evidence things are changing, and I can be aware of that. Today, I can do something prudent to make myself more resilient towards whatever may or may not happen. Tomorrow, if something happens, I can react accordingly.

The mind wants certainty, but that's not always available, so I observe the "wanting". The best I can do is act based on what's in front of me, and sitting in the negative emotions around existential thoughts doesn't help me, nor my family (it's natural to have them, but I acknowledge them and let them pass by). The best I can do is to do. If things change, I change. Everything in nature/life is ephemeral, and I have done my best throughout my life to set myself up to be as adaptable as possible.

Edit: To reduce this and get a bit Tao-ish, you don't need to know the exact shape of the river downstream as long as you're capable of steering when you get there.

Okay, but why get angry about it? Getting angry at things you can't do anything about is just silly, and if you can do something about it, get motivated instead of angry.
