I would be interested in semantic analysis of the communication from the involved online personas, similar to what was done for Satoshi, to point to a cultural direction. Would also be interesting to see if there were semantic style differences over time pointing to different people acting as the personas.
Since it would be quite a lot of code that has been committed as well, would also be interesting to see if code style differences could be found pointing to more people involved than only one.
Since when does does satisfying curiosity not provide any value. This has the potential to be a real life spy story ffs. Yeah you won't know anything for sure, that doesn't make this any less interesting.
Has anyone studied yet how well this kind of analysis holds up to simply asking GPT to rephrase your words? The whole thing goes out the window if that kind of attack works nowadays.
