It's not just that people just don't like change (unless it's the coin kind). Heck I can't get my Mom away from rotary phones not alone use a new kind of money for things.
that's normal, people are used to old things and even afraid of new technologies, they used old phone for example for 20 years and they won't go to new phone in days
same with bitcoin, we use fiat for ages now and it will be very, very hard to make people change to bitcoin because it is still new to them
