Satoshi is likely a graybeard.

Generally when we imagine a programmer, we think of a young man. But I think Satoshi is at minimum 50 years old.

Satoshi wrote sentences with two spaces after a period, which means he likely first learned how to type on a typewriter, not a keyboard. "Two spaces after a fullstop" is a habit that people learned in school in typewriter class.

Satoshi was likely already out of college before the early 1990s, because of his involvement in an old email list of computer scientists called the CypherPunks.

Satoshi's fascination with money might have derived from his age. People born in the 60s are old enough to be alive during the Gold Standard and the debate of money was a hot topic of debate from 1960-80
