At this point, people will adopt whether they'll want to or not.
Try telling that to an elderly woman who owned a smokeshop in downtown - First thing she said was Coins? wha wha wha? Coins like this?: (Pulls out a Sacajawea dollar) I said, No No bitcoins: The Future! - Instant Transactions with zero fees and instant transfer to your wallet - She then says - Oh no I don't use the internet at all. I'm not interested in that mess!
It was mentioned by the article writer that Bitcoiners' being in the community we are in, have the tendency to create a closed feedback loop (we all only see the good things in bitcoin and thus will only talk about these good things to each other over and over again until everyone shares the same feelings and beliefs) where we all see things as cheery and altruistic and positive - there will always be those who are successful with the current fiat system and they will not adopt until its too late (if bitcoin is shown to take over as the primary reference currency for transacting goods and services)
