The fact that the OpenClaw creators seemingly missed that parallel tells you everything you need to know about the project.
One of the robots ("moravecs" (amazing)) in Dan Simmons' Ilium was also crustacean formed: Orphu of Io (and his friend Mahnmut. Beat Charles to that particular weird coincidence-to-be by plus or minus a year!
It's not quite as memorable or as strong a theme as Accelerando laid down. But still quite a serendipity, imo.
Edit: oh, Charlie is down thread pointing out Lobsters was published on 2002, written 1998. Nice. https://news.ycombinator.com/item?id=48163630
All I need to know about the project is that the creators didn't read a relatively obscure SciFi book from 2005?
