Inventors have been fighting to take credit for technology's biggest ideas since at least the telephone, says Paul Saffo, a longtime Silicon Valley forecaster.
"Being first is heavily overrated in the technology space because all really good ideas end up being collaborative," says Saffo, of the San Francisco analysis firm Discern. "Ideas are cheap. It's the execution that matters. And if you look at where Facebook is now compared to where it started, it's a very difficult comparison. ... I wouldn't give a whole lot of credence to people who are showing up and claiming credit."
