If I showed you the top card of a deck, turned it over and put (apparently) that card in your hand, then told you I'd make the card change, everyone who posts on this site would think I'd done a double lift. And yes, chances are I would have done. However, if I did that for a layman (if I presented it well), I may well have given them a miracle they will remember for the rest of their life...in other words, I will have performed magic. We all know about double lifts, and we can all spot an edit on TV. Some people, however, get absorbed in the performance, because they haven't done the reading and study magicians have done, and they prefer to enjoy the effect.
Granted, some magicians only want to impress other magicians, which is fine. However, the people who make their living from magic perform for laymen, whether that's in restaurants, bars, on the street, on the stage, or on TV. Those people are performing to to entertain, not to show off their skills, in other words it makes absolutely no difference how they acheive their effects, as long as they elicit the intended reaction from the audience.
