Indeed. As others have noted, one of Gwern's many works reaches the front page of HN every few months - usually for its second or third time. Rather than finding this an annoyance, I enjoy these repeat postings; the ideas of which often represent ongoing community conversations (or spark new ones).

If this topic is of interest to you, then you might also enjoy this thread [0] from June, in addition to its home on GitHub [1].

I wasn't aware of the previous discussion, however, it's not surprising to me that this has shown up before.

Part of the reason I posted this is because a somewhat related article from the New York Times on decentralized computing made the front page today. I figured that HN readers interested in that might be interested in this essay as well. Plus, they might know of some further research on the topic which can help me learn more about the topic :)
