At this link on a _Gentlemen's Quarterly_ webpage is an article by David Copperfield titled "David Copperfield Breaks Down Magic Scenes from Movies."

At about the 4:25 spot David comments that
-----quote-----
"Many people say there's seven pieces of magic, seven effects, and it's 100% not true. I'm with my amazing staff, inventing new technology all the time."
-----unquote-----

By "many people," I guess David means "many magicians who write about magic theory"--like Dariel Fitzkee, Al Schneider, Eberhard Riese etc.

I'm curious about what people he's talking about and who he meant by "many people." Inventing new technology is not necessarily the same as inventing a new effect.

My first thought is that what he's saying is similar perhaps to what Dariel Fitzkee was getting at in _The Trick Brain_, that there are a limited number of magic effects, such as:
--productions
--vanishes
--transformations (in color, size, etc)
--multiplication
--defying gravity
--psychic phenomena
--invulnerability

I'm expecting my copy of David's History of Magic any day now. Maybe one of the things he writes about in the book are the seven effects that he mentioned in the GQ article.
