Curtis Yarvin (aka Mencius Moldbug) has speculated that Nick Szabo is Satoshi in his latest Grey Mirror article:

US 60/735,250 and the roots of Bitcoin

"I decided to save it in this cheap, reliable, secret way."

Yarvin is not nobody on this subject. He discusses his 2005 provisional patent application which hints at fixed supply “tokenomics”, and how he similarly had something like the precursor to React patented. He also links to conversation threads he had with Nick pre-Bitcoin on the topic. He is also the founder of Urbit, a Thiel-funded radical attempt to rethink computing (interesting, but destined to fail) and highly influential in that circle (Thiel/Andreessen/Vance et al - Silicon Valley “little tech” types) for his political and philosophical ideas. Not sure why he’s decided to dredge up this history now; he set it up with the React thing a few months ago, and could have made the point of his article without the Szabo commentary. I’ve listened to and read Yarvin for years, he is very intelligent and extremely well-read but I’ve long thought he is a snake in the grass - reading this gave me a bad vibe..
