Penn and Teller are no strangers to technology, but it hasn't impacted the core of their act. In a recent interview with USA Today, Penn Jillete (Teller isn't really the loquacious type) explains that, while all has evolved around it, magic has remained relatively unchanged. It's difficult to make magic work on TV and in online video, he laments. The mind will quickly shed doubt on what it's seeing, and in an age of Hollywood effects, it's tough to impress. "If you like the special effects of Guardians of the Galaxy, how are you going to be impressed with a card trick?" See that trick in person, however, and he says it's "untarnished."
