A sufficiently intelligent AI will have multiple ways to pose risk to humanity at large. For example an oopsie at a wetlab - very contagious virus with initially mild symptoms which kills its hosts only after they already had time to spread it further. But I would have to become super intelligent myself to give you precise blueprint for such a virus -- which is kind of the point
Also -- ASML lithography machine is only good at making chips. I can't believe you compared it to AI that can generalize across variety of tasks
If you for a second put yourself into the shoes of a person who thinks "the apocalyptic stuff" has even a 5% chance of literally happening in the real world, you might see how you wouldn't agree to move on from it.
The much more likely explanation to me is that people are just spitballing, either because they've watched too much sci-fi, or they have some weird counterintuitive agenda (e.g. Anthropic and OpenAI trying to position themselves as the amazing, trustworthy keepers of this dangerous technology before their IPOs).
But the discourse is dominated by paper clip experiment discussions and not let's say by the fact that new grads have an unprecedented difficult time getting jobs. Unsurprisingly one of those is a sexy hypothetical beneficial to power and the other one is not.
Multiple problems can be important, pointing a different one out doesn't invalid or take away from another one.
