Lots of people have deleted their home directories by accident. What you consider this an alignment problem?
How manypeople have deleted another user's hone directory, though? That's s the proper analogy IMO.
Yes. People are not aligned. They can and do harm themselves and others.
It's an alignment problem in the sense that it demonstrates the principle that today's AI systems cannot be trusted to reliably work towards the goals of their users. A small-scale alignment failure and a large-scale alignment failure are the same fundamental type of failure. Typically, large disasters come after smaller disasters which foreshadowed the disaster mechanism, but weren't taken seriously.
