When a spectator sees a magician perform this, if the magician uses proper showmanship,the magician should be able to convince the spectator that BLD is impossible.
Right, and that's what I have a problem with. I don't want someone to assume I'm cheating or doing a magic trick if I try to show them a BLD solve. I'm completely fine with a magician claiming that something like pushing one solid metal ring into another, making objects vanish, and so on, are impossible - because they are. But I'm not fine with magicians convincing the public that things which are very possible albeit difficult (and which people have spent many hundreds of hours getting good at!) are impossible. And, you know, it's not like this is the only trick in magic (or even the only Rubik's Cube trick in magic). I don't think all magic is wrong (not at ALL), I just think that this particular trick is damaging to the cube community.
If I were to do a BLD during a mind-reading act for people that don't know that I can solve a Rubik's Cube, I would peek to ensure that I finished the solve-for entertainment purposes only.
Good thing you have those italicized things there *cough kuti cough*.
But yeah, it's not as impressive to get a DNF, although it can be to your benefit if you get close (3 pieces off, for instance) and act like you don't know whether it's solved or not (which you don't).
I can't tell you how cool it is to have people amazed because they saw something that looks impossible. It's something that you have to experience yourself.
I've seen it (and it's also the same look people get when they see you do something that looks insanely difficult, like doing a cube OH in ~30 seconds). I guess as a matter of personal preference I'd rather get it from doing something which is impressive even if you know how to do it, but that's just me.
The magicians that invented these tricks make money from people buying their products. By learning for free, you are literally taking food off of their tables.
What if you figure a trick out yourself? I think, as a cuber, the "Enchanted Cube" trick is simple enough to be able to figure out yourself after seeing it a couple of times. Is that stealing?
