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?
Why would someone should start spending time on any other new topic?
Because people want to learn new things.
People are creative and curious, that's why they always discover new things.
Otherwise we would still be in the stone age.
Recently I heard something interesting:
"The stone age did not end because we ran out of rocks."
