Is this the #alternativefacts real world you're on about?  Because in the actual real world I live in, buying things like drinks at a cafe using Bitcoin the checkout person DOES wait for at least 1 confirmation, and the process isn't anywhere near as fast as you'd like people to believe.

Lets get a bit of realism in here, Bitcoin has a long long LOOOOONG way to go to challenge the likes of VISA as an everyday purchasing tool.
Would I like to see Bitcoin be as good as VISA? hell yes that would be amazing! Because I like Bitcoin, but does it currently?  hell no.   Should it?  Well, maybe or maybe not, maybe Bitcoin should never try to be like VISA at all, maybe thats not its calling.
