I tend to believe it's cognitive overload. I know folks who are open, intelligent and tech-wise, but they still find the learning curve(s) of this new tech difficult. If I put myself in their shoes, and imagine trying to make sense of all this Bitcoin -> Ethereum -> Bitshares -> Steem -> EOS -> Tron -> Hive connection, it would take me a while. I just wrote the name of the blockchains before the one we're using right now, if I would have to describe their tech, it would have take me days.
