I don't think the GUI is the key. Monero appeals most to extremely intelligent people who also have lots of money (aminorex, ArticMine). This type of guys will be the deciders of the price in the short (1 year) term. The masses come later.
I should refocus to the MiG thing. That is directing to the above segment. Here, my laborious scenario analyses did not receive even one comment. That is indicative that you aren't even interested in Monero here! We need more leaders, and we are bound to get them on board in the coming months.
I agree with you here with some qualifications. The official GUI(s) is only really possible with the database working well. And when those two things are in place we could see more "masses" come on board. We have to be ready.
The only danger here is some displacement by a crypto upstart with a gui etc. But that is an outlier.
By the way, I found your recent posts VERY interesting. And so thorough I felt no need to comment much. I do appreciate the effort.
