"terrified".... overused word. As a man I literally can't relate. I get terrified when I see a shark next to me in the ocean. I get impatient when code is hard to debug.
Step 1: Start looking beyond your code, as the stuff beyond your code is looking at you.
Its existential dread, of being useless and of not being able to thrive.
Its being compared to that of a slop machine, and billionaires claiming that its better than you are in all ways.
Its having integrity in your work, but the LLM slop-machines can lie and go "You're actually right (tells more lies)".
It all comes down to that LLMs serve to 'fix' the trillion dollar problem: peoples wages. Especially those engineers, developers, medical, and more.
We're pretty good at naming fear when it has a physical trigger. We're much worse at naming the unease that comes from watching something you care about get quietly hollowed out over time. That doesn't make it melodrama, just a different category of discomfort.
