I guess I don’t really see the internet as a disaster, sure it brings issues but so did factories and mass production, and so will AI.
For Internet-related disasters where people died, see [1].
I would bet that there will be AI-related disasters. Arguably the US bombing a school in Iran counts, though it seems to be due to organizational issues, too.
