The technologie and Protocol of IOTA is very complex. I can't say if this technologie is implementable but I hope it. What worries me is why it is so easy to write the complex code and so diffcult to write the easiest part- the GUI. I hope this official statement is true.
Man, are you serious? You are either trolling or misinformed. There is absolutely no problem with developing the GUI, none what so ever. Like you said: it's easy. But GUI is about the
G. We had a GUI ready in December actually, a very rough one that CfB put together in an afternoon or two, but the community (after seeing screenshots) expressed wishes for a beautiful GUI(CfB is a hardcore backend dev, not frontend graphic designer), we agreed with this as first impression is important. So then we hired a well renowned design/UI firm called
www.creativeda.sh who started work (albeit a bit slow), then suddenly they inform us that they lost their developer (he quit). So now we had wasted a month and had to start all over again, that's life, so we did, then we hired
www.danwarfel.com who also has a very solid portfolio. What happens? He disappears for 3 weeks straight. So of course, had to fire him, find new dev, which is very soon to be done with the UI now.
So as you can see, it has nothing to do with being hard, it was just a series of extremely unfortunate events out of our control. This is usually called Murphy's law.
