I meant early adopters of cryptocurrency, versus second or third wave newcomers, versus the type of people joining in the last couple years. Each population definitely has their own levels of sophistication and interests by large.

As an example I don’t think Hal would have much interest in shibemoon pump and dump telegram channels and likewise most people joining today don’t have much interest in the implementation details of rootstock.

I knew Hal Finney. He was a special case, and not representative of anyone else I know.

For example, at the last minute he decided to enter a Gomoku-playing computer programming contest. He learned Gomoku and wrote a program that trashed the competition (including the MIT entry) in a weekend.

He also cared about CO2 emissions and energy efficiency of Bitcoin, which apparently the vast majority of other participants did not, or do not. [1]

I didn't know he had a twitter account! Added myself to his 39,000 followers. I infer a lot of people miss him.

Agreed, nice to see it's still around.
