Magic isn't deteriorating. If anything, there is a boom. David Blaine, Criss Angel, and Derren Brown have all brought magic into mainstream view. Magic is cool and no longer geeky, as it were.
With this comes a price, though. Whenever something becomes popular, everyone wants to do it. They believe that because they do something popular, they themselves can become popular. This is why there are so many videos of people performing effects on *big gasp* YouTube. That being out of my system...
Ive been performing magic since I was 7, and Ive been a member of the IBM since I was 10. I'm now 22. Sadly, during the end of High School and some of college, I had a falling out of magic (trust me, this is going somewhere...). However I am back now because I felt a part of me was missing. When I stopped, there was no magician who was afraid to get their hands dirty. Going to the magic shop and buying a packet trick to perform was fun. Things which required setup were not looked down upon. Moreso, props, gimmicks, and the like were not considered "n00bish."
Magic now, at least with those who are starting to get into it are falling into the instant gratification pit. They want an effect. Not any effect, it must be street magic. It must be something great that will fools everyone. And oh yea, if the setup is more than 10 seconds, it isn't a good effect. I've seen people turn down great effects because there was a bit of setup. It kills me to see this. It must also deal with cards, coins, or something that everyone has on them. As when I started, I had to attend lectures, go to Magic meetings at my local IBM ring, and learn off of homemade VHS' that I bought directly from the creators (reminding me of when I ran in late one night after class in Middle School to my magic shop to to hear Lennart Green speak) or from a magic shop. Now, though I am not complaining in the least, we have instant downloads and online ordering. This means many people who were previously unable to gain access to knowledge of magic now has very easy access.
I am not at all saying every new magician falls into this pattern of thinking. I am just saying a lot of younger kids who are starting out do this. Ive seen posts over at other magic sites of people getting annoyed they bought an effect, and it had setup. Or asking if an effect requires setup and if it does, they do not want to touch it. Also, performing an effect without being able to fool yourself in the mirror and do it in your sleep was unheard of when I started. Now, it seems as soon as they memorize how to do an effect, they believe its time to. Just out of curiosity, who still practices their sleights in the mirror?
Anyway, even with all of this, we can keep magic strong. An effect without practice or patter designed to fit you is nothing. It's a copy. However, if you take an effect, practice it until you dream about it, and design your own patter, the same effect little bobby performed on YouTube that got no reactions will gain you great reaction because you put time into it and made it yours.
Anyways, just my .02
