How can a mainstream journalist figure out Satoshi — without studying Bitcoin physics to exclude all cryptographers first? If you want to figure out Satoshi — you must first understand Bitcoin roots in physics, not cryptography or economics. Then be good at combining things, which suggests a chemistry background. Finally, Bitcoin physics is not mainstream — it is more advanced What is simplest evidence to grok new Bitcoin physics? The distributed core of Bitcoin across miner network rejects black hole singularity formation. Ask how something expanding larger and larger, also grows stronger and stronger — not collapse, like black hole? This distributed core physics suggests Satoshi had background at NSA, CIA, DOE or combination. If you want to narrow it down further — Satoshi is/was a great writer. Satoshi was not a cryptographer. That was just the result of a polymath.
