I wouldn't think informed people are afraid of an "evil AI", it's about then complying to prompts in ways the prompter wouldn't expect - because of weak target systens, or the agent was not sandboxed enough, or sandboxing was done carelessly. All current hacking cases are like this, imagine the same with weapon systems.

A lot of young people are pretty unhappy with the state of the world and the future they’ve been given. I don’t really blame them for targeting various different things that represent that future.
