Can you please not post AI-generated or AI-edited comments to HN? It's not allowed here - see https://news.ycombinator.com/newsguidelines.html#generated and https://news.ycombinator.com/item?id=47340079.

Of course, it's impossible to know for sure what was LLM processed or not, but some of your posts (like this one) have been getting classified that way.

I'm sure it's a great place to live and work, but can you please edit out swipes from your comments here, as the site guidelines ask (https://news.ycombinator.com/newsguidelines.html)?

Your post would have been just fine without that first bit.

Thanks! changed from https://www.ecb.europa.eu/euro/banknotes/future_banknotes/ht... above. I've put the original URL in the toptext.
