Wozniak, 61, was the star turn at the penultimate performance in Washington of "The Agony and the Ecstasy of Steve Jobs," monologist Mike Daisey's controversial two-hour expose of Apple's labor conditions in China.
In a post-performance dialogue with Daisey and audience members, Wozniak held forth on topics as varied as public education (he once did a stint as a school teacher) and reality TV (having appeared on "Dancing with the Stars").
But the engineering wizard behind the progenitor of today's personal computer, the Apple II, was most outspoken on the shift away from hard disks towards uploading data into remote servers, known as cloud computing.
"I want to feel that I own things," Wozniak said. "A lot of people feel, 'Oh, everything is really on my computer,' but I say the more we transfer everything onto the web, onto the cloud, the less we're going to have control over it."
