I absolutely refuse to worry.
All my childhoood we were told the atomic bomb would be the end of us, when WW3 started.
No-one appreciated my mother's mundane consideration, that throwing atomic bombs about makes no sense if you are trying to conquer the world, or just your neighbouring country, which is usually why anyone starts a war, but I still think she had a point.
Later that we were ruining the environment (true enough) and that climate change and before that DDT would cause famine and the ultimate destruction of mankind. Quite true if we and our governments do not react in time.
Every generation has their bogey-men. AI is the present new bogey. It may destroy mankind, or it may not. So we need to find out if this is a re asonable fear or noot, and how it can be controlled as some of the other threats have been or are being.
