I think your right, the word to have in mind here is "change".

People were fond of stone tablets and animal skins for writing until the traditional paper we all know was developed. Paper was good, but handwriting books were tiresome and weary. The printshop was then invented. Same for cars, trains, the Internet...every major change brings new challenges to the table. Bitcoin is more than just money, it´s the idea behind it that gives it value. (and the banks, of course, are the ones getting challenged this time)
