Fuck AI

I don’t think AI is actually that good at summarizing. It doesn’t understand the text and is prone to hallucinate. I wouldn’t trust an AI summary for anything important.

This right here. Whenever I've tried using an LLM to summarize, I spent more time fact-checking it (and finding the inevitable misunderstandings and outright hallucinations—they're always there for anything of substance!) than I'd spend writing my own damned summary.

There is, however, one use case I've found where LLMs work better than alternatives ... provided you do due diligence. To put it bluntly, Google Translate and its ilk of similar slop from Bing, Baidu, etc. suck. They are god-awful at translation of anything but straightforward technical writing or the most tediously dull prose. LLMs are far better translators (and can be instructed to highlight cultural artifacts, possible transcription errors, etc.) ...

... as long as you back-translate in a separate session to check for hallucination.

Oh, and Google Translate-style translators really suck at Classical Chinese. LLMs do much better (provided you do the back-translation check for hallucination).
