People are scared because they think they could lose their jobs. Even if they say out loud they don't think it will happen and that they think AI is useless. They need AI to fail for peace of mind.

If anything they're most at risk for losing their job due to a stubborn refusal to adopt technology. What people don't realize is that we don't live in an ideal world where the optimal solution is the only way. Even if LLMs are less than perfect, there's a scenario where it remains commonplace because it's what's in style. The stubborn abstainers will find themselves left behind when everyone else is leveraging it to complete mundane tasks much faster and checking the work.

We already live in a world full of cumbersome enshittified technology. There's nothing we can do but make do with what we have. At this point people are dreaming if they think the AI bubble will pop and the technology will be shelved. It's not going away. It's already demonstrated usefulness. That it's not turning a profit is a different story.

Maybe some others are simply scared that they don't have the expertise to check the work of LLMs in the first place.
