[1] some people seem to just "get" btc almost as soon as they are introduced to it,
[2] others simply don't or
[3] become hostile without understanding BTC tech.
[4] Become hostile and do understand the tech.
The demarcation lines seem to me quite stark. Any theories as to why this is?
(I understand [5] those who just don't get it or are not interested, )
I think people have different levels of understanding and how they react to new tech. Some people are open to new technologies and are willing to try them out but others are not. Some people truly believe technology can change things over time and some people are not buying that. Long story short, people have different options over new things including science and technology.
