That seemed amazing to me because it would’ve meant Google found the comment, integrated it into thier index, and then made that index available, all within three hours. I know Google is good but are they that good?

I googled “xml startup business example” their AI summarized an “xml startup” as “a business using XML as a core technology” and gave the business below as an example startup.

I didn’t see any reference to the hacker news comment.

Most of the links google provided below the AI summary were about how to configure various XML tools to… startup. Standard link farm stuff. :)

Google is usually pretty on top of fast-changing sources like HN. My mind was blown more when I saw that ChatGPT seemed to ingest and regurgitate an HN comment of mine as an answer within 10-15 minutes of my posting (see the thread in https://news.ycombinator.com/item?id=42649774). Sadly this is no longer verifiable as the answer does not match my comment, but at least it correctly answers the original request, which it did not prior to my response.

I routinely see Google indexed HN comments within one or two hours of posting so not at all surprised by this.

EDIT: In fact I see your comment as the 5th result or so searching "XML Startup" in quotes haha.
