I like them as non-profit tools for personal use, but the hatred is justified IMO because we’re already seeing people with writing jobs lose that job and get replaced by an LLM and an “editor” who is paid less than the writer was.

That's capitalism in all of its glory. People never mattered to the ones who want to make money; they just want want to as much profit as possible with the minimal investment. Someone at work created a tool that turns a work day of painstating tasks into a 5 minute wait? Fire the people, keep the tool. You may call LLMs or AIs enablers, but it's like hating baseball bats because some use them to crack open skulls instead of hitting baseballs.

Regarding the verification of AI-generated content, I just can say I agree, but it's going to be hard to detect.
