Which is pretty unfortunate for those that want to learn. I used to enjoy writing documentation at work, it was my favorite part of the job. And it did feel like it benefited me more than it benefited all the people that were (or weren't) reading my documentation. Now I can't really justify spending much time on docmentation when LLM's can do it in a fraction of the time and it's "good enough"
Is it perfect? No. But it suffices most of the time in a pinch.
Can’t speak to the nuke industry, but it’s pretty good at aviation related things.
