A GUI is of critical importance for the next level of adoption.
How many Bitcoin users do you think still use QT?I run QT still
is that bad?Me too! Id does what it is supposed to do. For Monero, I also have the CLI wallet installed, but I would never get my wife to use it. But she can handle Bitcoin-QT without problems -> GUI wallet is a big deal IMHO.
BTW: there may be a small, shy triangle breakout. Let's see how it develops.
I think us techies tend to underestimate the issue with the CLI wallet. Its not so much that people can't figure out how to use it, its not difficult and most people could. But because we are dealing with money there is apprehension about using something that is not super easy and straight forward, users might think they are more likely to screw something up and lose their funds.
