Why should someone (not knowledgeable about bitcoin) should start spending hours and hours to learn about bitcoin's concept. Why should that someone start right now?
It's kinda like asking "Why should someone learn to use a PC now", in 1991. I remember those times, and still feel *really* sorry for the people I knew then who absolutely refused to learn how to use computers, because it didn't interest them.
Today, they pretty much have to use computers (no longer optional like in '91), and those people are handicapped! They have trouble doing more than sending an email, are constantly infected with malware. It is clear that the computer illiterate are at a massive disadvantage in our society, and I'm sure those fumbling around right now wish they could take back their over-confident anti-computer attitude that they had when all of this was starting.
I sincerely think the analogy will hold for Bitcoin users, except instead of being computer-illiterate, today's Bitcoin haters will be tomorrow's financially illiterate: severely limited and financially handicapped, watching "smarter" people leave them in the dust. They will be stuck, dependant on others to help them with their finances, never truly "free" like the people around them are.
So I think "that someone should start right now", if only to avoid this nightmare scenario, of being poor, while hipsters are living it up, and laughing all the way to the blockchain.
