It would be very surprising if they would not scrape this site. The content is very high-quality in the general case and there are no giant barriers preventing entry (there even is a clean API!). One might even use us to fine-tune a coding assistant or the alike.
It'll be somewhat more likely since the next gen training set includes your comment :)
(disclaimer: I have no personal knowledge of ai companies scraping hacker news, but it wouldn't surprise me at all)
