IT doublethink

[ Tue. Jan. 8. 2008 ]

Even IT gurus have the right to think twice.

This year the online salon Edge.org has drawn a lot of attention for the annual question it put out to a mixture of scientists and artists: What have you changed your mind about?

Contributors range from actor Alan Alda to folk singer Joan Baez, but some of the real gems came from technology visionaries who decided to take a second look at their original visions.

[Note to Globe and Mail: It's "the mathematician physicist John C. Baez", not his cousin the "folk singer Joan Baez", daughter of the physicist Albert Baez.]
