Online translators seem to have gotten a lot better! Your comment, translated to Mandarin and back:

是的，我也会这样做。每次我尝试分段落写东西，收件人最后都会有一半内容没有回应。感觉他们读到第一个问题就停止阅读了。

这种 AI 扩写和总结让我想起了早期网络翻译刚出现的时候：你把一段话翻译成另一种语言，再翻译回原来的语言，结果得到的内容却完全变了。

Yes, I do this too. Whenever I try to write something in paragraphs, the recipient inevitably ends up not responding to half of what I wrote. It feels like they get to the first question and just stop reading.

This AI expansion and summarization reminds me of the early days of online translation, when you could translate something into another language and then translate it back, only to end up with something completely different.
