Industry legend Steve Wozniak foresees "horrible problems" with cloud-based computing, particularly around ownership.

Wozniak gave a gloomy assessment of the cloud in a question and answer session with the audience of the performance piece "The Agony and the Ecstasy of Steve Jobs", in which he co-starred.

"I really worry about everything going to the cloud," he said.

"I think it's going to be horrendous. I think there are going to be a lot of horrible problems in the next five years."

"With the cloud, you don't own anything. You already signed it away. I want to feel that I own things," continued Wozniak.

"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."
