No other human activity poses this level of danger. I do heed the warnings, but this comes across as detached hyperbole. See: global warming, nuclear weapon development, wealth inequality, war, technology dependence, etc. Also, this has nothing to do with LLMs or computers. Like all things, this is about humans.
AI is an exception. We're already losing understanding (although we never fully had it in the first place), and we're losing control (see jailbreaks/hacks etc.).
We're still far from the doomsday scenario because AI 1. is not developed enough yet, 2. can't really replicate itself, and 3. has very limited means to act.
But: 1. its intelligence is developing quickly, 2. hardware capable of "hosting" it is slowly being developed, and 3. it will likely gain access to increasingly powerful means of acting in the physical world (this is already happening in the digital world).
Once AI becomes intelligent enough (it doesn't strictly need to be AGI), has the substrate on which to exist, and has more means to act, we'll essentially have a new species on Earth - one more capable than humans and potentially determined to kill humans at some point.
And for those who believe airgapping is a valid safety measure: read https://xkcd.com/538. AI will be able to threaten and manipulate people.
