Why the are you getting more text than you can physically review at your job?

Regulatory required documented training, old conservative company.

How are you sure LLMs are not missing anything if nobody actually has the time to read through all the text?

You're not. Neither do the humans tasked with the job do a 100% thorough review. Side by side, the LLM catches more flaws than the humans do.

produce proper specifications that developers would implement without wasting time on specifications containing garbage.

Sounds nice. We've got ~500 employees at our "site" (which is now distributed across 3+ states with remote workers), of those, about 8 do software development, so developers end up doing virtually all of the translation of customer "needs" to specifications / requirements. We also have a marketing department that changes their mind about twice as fast as the product development / delivery cycle.

If I leave a webpage with a calculator running unattended it won’t magically persuade a random visitor into commiting suicide.

That's a touchy subject. A friend of ours recently had her son die of drowing in his bathtub, he was epileptic, had a seizure and fell in the tub. There was no suicide note, it was ruled an accident. He used ChatGPT to write his own obituary, as well as a book explaining his life from his perspective - each seizure was "taking away a little of who he was," and the seizures were getting more frequent, none of the treatments or medications slowed them. It's pretty clear, to me, that he was going to commit suicide and/or die soon with or without ChatGPT. After he passed, his mother had a ton of grief / guilt about not being closer with him in his life, but then... he actively pushed her away, even violently. It's doubtful he would have written or expressed what he did as completely without ChatGPT assistance - how much was him, how much was LLM hallucination? Does it really matter? He wrote the book, and he put it where she would find it.

The next time you go driving, count the oncoming cars. When you get to 100, realize this: statistically, one - maybe two - of the drivers of those oncoming 100 cars will, eventually, end their life by suicide. And those are just the deaths officially classified as suicide. Engagement with ChatGPT undoubtedly works both ways, some cases accelerating the process or even causing them to take their lives when they wouldn't have, and other cases slowing or stopping the pursuit of suicide altogether. It's going to be hard to say if Chatbots or other world events drive the statistical changes starting a couple of years ago. The data isn't clear yet, but the concerns have certainly been raised, and I would assume the supportiveness of Chatbots should improve as a result in the future.
