Re: I wonder how many people have actually solved the cube?
Back in 1981 I was actually in competition with my father to solve the cube, and he beat me by 2 weeks, and even then once he figured it out he refused to show me, I love my father, but sometimes he is a real pain! (yes he is still alive at 91)
So I figured I would get even with him, when they came out with a 4x4 cube I got a couple of them and we re-started the competition, and he beat me again! Ugggg! But I did solve the 4x4 eventually, it took my father about 4 months to figure it out, and it took me 6 months.
Two years ago my adult daughter got me a 7x7 cube for Christmas and I have yet to figure it out. It is devilishly hard, or maybe my brain is getting worn out, but I refuse to give up. Getting old sucks, but I guess it beats the alternative!
