All this talk about the necessity and convenience for mass adoption is nonsense at this point in time.
Mass adoption in the literal sense is a long way out. The only group that matters at the moment are people who are already into crypto or curious enough to venture into it. They are few, and their hearts and conviction will have to be conquered.
It is them who will be the ambassadors for when larger adoption actually becomes a possibility. It is their choices which will be the choices of the masses. It is their competence which will help the rest of the world to ease into it.
The GUI is important, of course. However it is not important for the masses, but to help in carving out a sufficiently large group from this mess that makes up
crypto: Idealists, techies, economists, thieves, liars... and all the "normal" people stumbling into this space thinking WOW wtf is going on in here this looks cool!
Just as I did a few years ago.
A group (or market share for the cynics) large enough to gain the necessary inertia to rocket past the cesspool of failed money grabbing shiny shit projects that make up 95% of this habitat.
