It wasn't just 'digital currencies' Szabo pioneered either. He did the earliest work on smart contracts too. Smart contracts are multi-disciplinary spanning law, cryptography, economics, programming, accounting, and game theory. It's the kind of insight only a polymath would have. People who only know a little about Bitcoin think it's like a currency. But built inside it is a scripting system that lets you program the conditions for moving around coins. This allows for incredibly elaborate extensions to be made to the system without having to change its core rules.

Satoshi was also interested in smart contracts. In fact, there was early work in the Bitcoin code base where satoshi had designed an entire online market system. I've never seen the code for this myself or what features it had. But to me this is so far ahead of everyone else and solidifies much of what would be built on top of blockchain systems that it's scary. So Satoshi builds the groundwork for practically the next 10 years worth of complex, technical discussions. Satoshi even knew that time-locked transactions would be useful so it was part of Bitcoin too.
