It's fun to read some of these historic comments! A while back I wrote a replay system to better capture how discussions evolved at the time of these historic threads. Here's Karpathy's list from his graded articles, in the replay visualizer:

Comment dates on hn frontend are sometimes altered when submissions are merged, do you handle this case properly?

It is handled on the Unlurker front page (you will see a little note that says “time adjusted for second chance”). The replay doesn’t do any adjustment for it, but I think that makes it reflect the reality of when the comments came in since the adjustments are like a temporary bump
