The magic world needs more people thinking about performance, not tricks.
Michael already has tons of free content on his YouTube channel that specifically deals with performance, creativity, being professional, etc. Scott Alexander is also putting out material that is essentially a course being a stand-up performer. I think there is plenty of content out there already on performance, creativity, and magic theory. The issue is the demographic of people that purchase magic online. I'm betting that something with a hyped up trailer about a coin splitting in half and then restoring is going to sell much better than a course on being a stand up performer. (Note: I'm not bashing that effect, I will probably pick it up, I just wanted to give a recent example of a newer release competing against Scott Alexander's release).
My theory as to why this is happening is most people are using magic as a way to benefit themselves rather than benefiting others (i.e. live performances with spectator participation). A lot of this is facilitated by mediums such as YouTube, Instagram, Snapchat, and even this site to an extent. The majority of "magicians" (I'm using that term very loosely) buy whatever they see is cool in a trailer and want to be just as cool as that trailer is. They will click "add to cart" and shoot a quick performance to a camera and collect likes and followers over it. The minority of the magic consumer population is actual working magicians that want to buy something to build on their current act. This demographic typically buys less than the majority so magic companies are starting to produce and market products that appeal to the majority and not the minority (i.e. trailers with no live performances but look amazing).
A lot of this is also the magic industry's fault too. None of the big magic sites I follow have any sort of appreciation for live performances or celebrating working magicians. Most of what I see being celebrated is what can look good on camera and basically fool only a camera. I know it's much easier to sell products that way but it is also the cause of why consumer interests are no longer about performances (second only to social media being the main cause of it).
